    #     * `Aws::Credentials` - Used for configuring static, non-refreshing
    #       credentials.
    #
    #     * `Aws::SharedCredentials` - Used for loading static credentials from a
    #       shared file, such as `~/.aws/config`.
    #
    #     * `Aws::AssumeRoleCredentials` - Used when you need to assume a role.
    #
    #     * `Aws::AssumeRoleWebIdentityCredentials` - Used when you need to
    #       assume a role after providing credentials via the web.
    #
    #     * `Aws::SSOCredentials` - Used for loading credentials from AWS SSO using an
    #       access token generated from `aws login`.

    #     checksum errors, networking errors, timeout errors, auth errors,
    #     endpoint discovery, and errors from expired credentials.
    #     This option is only used in the `legacy` retry mode.
    #
    #   @option options [Integer] :retry_max_delay (0)
    #     The maximum number of seconds to delay between retries (0 for no limit)

    #       unsuccessful retries a client can make.
    #
    #     * `adaptive` - An experimental retry mode that includes all the
    #       functionality of `standard` mode along with automatic client side
    #       throttling.  This is a provisional mode that may change behavior

    #
    #     * `Aws::SSOTokenProvider` - Used for loading tokens from AWS SSO using an
    #       access token generated from `aws login`.
    #
    #     When `:token_provider` is not configured directly, the `Aws::TokenProviderChain`
    #     will be used to search for tokens configured for your profile in shared configuration files.
    #
    #   @option options [Boolean] :use_dualstack_endpoint
    #     When set to `true`, dualstack enabled endpoints (with `.aws` TLD)

    #     number of seconds to wait for response data.  This value can
    #     safely be set per-request on the session.
    #
    #   @option options [Float] :http_idle_timeout (5) The number of
    #     seconds a connection is allowed to sit idle before it is
    #     considered stale.  Stale connections are closed and removed
    #     from the pool before making a request.
    #
    #   @option options [Float] :http_continue_timeout (1) The number of
    #     seconds to wait for a 100-continue response before sending the
    #     request body.  This option has no effect unless the request has

    #   on the stack. Provided that users have permission to operate on the
    #   stack, CloudFormation uses this role even if the users don't have
    #   permission to pass it. Ensure that the role grants least permission.
    #
    #   If you don't specify a value, CloudFormation uses the role that was
    #   previously associated with the stack. If no role is available,
    #   CloudFormation uses a temporary session that's generated from your

    #
    # @option params [Array<String>] :resources_to_skip
    #   A list of the logical IDs of the resources that CloudFormation skips
    #   during the continue update rollback operation. You can specify only
    #   resources that are in the `UPDATE_FAILED` state because a rollback
    #   failed. You can't specify resources that are in the `UPDATE_FAILED`
    #   state for other reasons, for example, because an update was canceled.
    #   To check why a resource update failed, use the DescribeStackResources
    #   action, and view the resource status reason.
    #
    #   Specify this property to skip rolling back resources that
    #   CloudFormation can't successfully roll back. We recommend that you [
    #   troubleshoot][1] resources before skipping them. CloudFormation sets
    #   the status of the specified resources to `UPDATE_COMPLETE` and
    #   continues to roll back the stack. After the rollback is complete, the
    #   state of the skipped resources will be inconsistent with the state of
    #   the resources in the stack template. Before performing another stack
    #   update, you must update the stack or resources to be consistent with
    #   each other. If you don't, subsequent stack updates might fail, and
    #   the stack will become unrecoverable.
    #
    #   Specify the minimum number of resources required to successfully roll
    #   back your stack. For example, a failed resource update might cause
    #   dependent resources to fail. In this case, it might not be necessary
    #   to skip the dependent resources.
    #
    #   To skip resources that are part of nested stacks, use the following
    #   format: `NestedStackName.ResourceLogicalID`. If you want to specify
    #   the logical ID of a stack resource (`Type:
    #   AWS::CloudFormation::Stack`) in the `ResourcesToSkip` list, then its
    #   corresponding embedded stack must be in one of the following states:
    #   `DELETE_IN_PROGRESS`, `DELETE_COMPLETE`, or `DELETE_FAILED`.
    #
    #   <note markdown="1"> Don't confuse a child stack's name with its corresponding logical ID
    #   defined in the parent stack. For an example of a continue update

    #
    # @option params [Array<String>] :capabilities
    #   In some cases, you must explicitly acknowledge that your stack
    #   template contains certain capabilities in order for CloudFormation to
    #   create the stack.
    #
    #   * `CAPABILITY_IAM` and `CAPABILITY_NAMED_IAM`
    #
    #     Some stack templates might include resources that can affect
    #     permissions in your Amazon Web Services account; for example, by
    #     creating new Identity and Access Management (IAM) users. For those
    #     stacks, you must explicitly acknowledge this by specifying one of
    #     these capabilities.
    #
    #     The following IAM resources require you to specify either the
    #     `CAPABILITY_IAM` or `CAPABILITY_NAMED_IAM` capability.
    #
    #     * If you have IAM resources, you can specify either capability.
    #
    #     * If you have IAM resources with custom names, you *must* specify
    #       `CAPABILITY_NAMED_IAM`.
    #
    #     * If you don't specify either of these capabilities, CloudFormation
    #       returns an `InsufficientCapabilities` error.
    #
    #     If your stack template contains these resources, we suggest that you
    #     review all permissions associated with them and edit their
    #     permissions if necessary.

    #
    #   * `CAPABILITY_AUTO_EXPAND`
    #
    #     Some template contain macros. Macros perform custom processing on
    #     templates; this can include simple actions like find-and-replace
    #     operations, all the way to extensive transformations of entire
    #     templates. Because of this, users typically create a change set from
    #     the processed template, so that they can review the changes
    #     resulting from the macros before actually creating the stack. If
    #     your stack template contains one or more macros, and you choose to
    #     create a stack directly from the processed template, without first
    #     reviewing the resulting changes in a change set, you must
    #     acknowledge this capability. This includes the [AWS::Include][9] and
    #     [AWS::Serverless][10] transforms, which are macros hosted by
    #     CloudFormation.
    #
    #     <note markdown="1"> This capacity doesn't apply to creating change sets, and specifying
    #     it when creating change sets has no effect.
    #
    #      If you want to create a stack from a stack template that contains
    #     macros *and* nested stacks, you must create or update the stack
    #     directly from the template using the CreateStack or UpdateStack
    #     action, and specifying this capability.

    #
    # @option params [Array<String>] :capabilities
    #   In some cases, you must explicitly acknowledge that your stack
    #   template contains certain capabilities in order for CloudFormation to
    #   create the stack.
    #
    #   * `CAPABILITY_IAM` and `CAPABILITY_NAMED_IAM`
    #
    #     Some stack templates might include resources that can affect
    #     permissions in your Amazon Web Services account; for example, by
    #     creating new Identity and Access Management (IAM) users. For those
    #     stacks, you must explicitly acknowledge this by specifying one of
    #     these capabilities.
    #
    #     The following IAM resources require you to specify either the
    #     `CAPABILITY_IAM` or `CAPABILITY_NAMED_IAM` capability.
    #
    #     * If you have IAM resources, you can specify either capability.
    #
    #     * If you have IAM resources with custom names, you *must* specify
    #       `CAPABILITY_NAMED_IAM`.
    #
    #     * If you don't specify either of these capabilities, CloudFormation
    #       returns an `InsufficientCapabilities` error.
    #
    #     If your stack template contains these resources, we recommend that
    #     you review all permissions associated with them and edit their
    #     permissions if necessary.

    #     * [ AWS::IAM::AccessKey][1]

    #
    #     For more information, see [Acknowledging IAM Resources in
    #     CloudFormation Templates][8].
    #
    #   * `CAPABILITY_AUTO_EXPAND`
    #
    #     Some template contain macros. Macros perform custom processing on
    #     templates; this can include simple actions like find-and-replace
    #     operations, all the way to extensive transformations of entire
    #     templates. Because of this, users typically create a change set from
    #     the processed template, so that they can review the changes
    #     resulting from the macros before actually creating the stack. If
    #     your stack template contains one or more macros, and you choose to
    #     create a stack directly from the processed template, without first
    #     reviewing the resulting changes in a change set, you must
    #     acknowledge this capability. This includes the [AWS::Include][9] and
    #     [AWS::Serverless][10] transforms, which are macros hosted by
    #     CloudFormation.
    #
    #     If you want to create a stack from a stack template that contains
    #     macros *and* nested stacks, you must create the stack directly from
    #     the template using this capability.
    #
    #     You should only create stacks directly from a stack template that
    #     contains macros if you know what processing the macro performs.
    #
    #      Each macro relies on an underlying Lambda service function for
    #     processing stack templates. Be aware that the Lambda function owner
    #     can update the function operation without CloudFormation being
    #     notified.
    #
    #     For more information, see [Using CloudFormation macros to perform
    #     custom processing on templates][11].

    #
    # @option params [Array<String>] :resource_types
    #   The template resource types that you have permissions to work with for
    #   this create stack action, such as `AWS::EC2::Instance`, `AWS::EC2::*`,
    #   or `Custom::MyCustomInstance`. Use the following syntax to describe
    #   template resource types: `AWS::*` (for all Amazon Web Services
    #   resources), `Custom::*` (for all custom resources),
    #   `Custom::logical_ID ` (for a specific custom resource),
    #   `AWS::service_name::*` (for all resources of a particular Amazon Web
    #   Services service), and `AWS::service_name::resource_logical_ID ` (for
    #   a specific Amazon Web Services resource).
    #
    #   If the list of resource types doesn't include a resource that you're
    #   creating, the stack creation fails. By default, CloudFormation grants
    #   permissions to all resource types. Identity and Access Management
    #   (IAM) uses this parameter for CloudFormation-specific condition keys
    #   in IAM policies. For more information, see [Controlling Access with
    #   Identity and Access Management][1].
    #
    #
    #
    #   [1]: https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-iam-template.html
    #
    # @option params [String] :role_arn
    #   The Amazon Resource Name (ARN) of an Identity and Access Management
    #   (IAM) role that CloudFormation assumes to create the stack.
    #   CloudFormation uses the role's credentials to make calls on your
    #   behalf. CloudFormation always uses this role for all future operations
    #   on the stack. Provided that users have permission to operate on the
    #   stack, CloudFormation uses this role even if the users don't have
    #   permission to pass it. Ensure that the role grants least privilege.
    #
    #   If you don't specify a value, CloudFormation uses the role that was
    #   previously associated with the stack. If no role is available,
    #   CloudFormation uses a temporary session that's generated from your
    #   user credentials.
    #
    # @option params [String] :on_failure
    #   Determines what action will be taken if stack creation fails. This
    #   must be one of: `DO_NOTHING`, `ROLLBACK`, or `DELETE`. You can specify
    #   either `OnFailure` or `DisableRollback`, but not both.
    #
    #   Default: `ROLLBACK`
    #
    # @option params [String] :stack_policy_body
    #   Structure containing the stack policy body. For more information, go
    #   to [ Prevent Updates to Stack Resources][1] in the *CloudFormation
    #   User Guide*. You can specify either the `StackPolicyBody` or the
    #   `StackPolicyURL` parameter, but not both.
    #
    #
    #
    #   [1]: https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/protect-stack-resources.html
    #
    # @option params [String] :stack_policy_url
    #   Location of a file containing the stack policy. The URL must point to
    #   a policy (maximum size: 16 KB) located in an S3 bucket in the same
    #   Region as the stack. You can specify either the `StackPolicyBody` or
    #   the `StackPolicyURL` parameter, but not both.
    #
    # @option params [Array<Types::Tag>] :tags
    #   Key-value pairs to associate with this stack. CloudFormation also
    #   propagates these tags to the resources created in the stack. A maximum
    #   number of 50 tags can be specified.
    #
    # @option params [String] :client_request_token
    #   A unique identifier for this `CreateStack` request. Specify this token
    #   if you plan to retry requests so that CloudFormation knows that
    #   you're not attempting to create a stack with the same name. You might
    #   retry `CreateStack` requests to ensure that CloudFormation
    #   successfully received them.
    #
    #   All events initiated by a given stack operation are assigned the same
    #   client request token, which you can use to track operations. For
    #   example, if you execute a `CreateStack` operation with the token
    #   `token1`, then all the `StackEvents` generated by that operation will
    #   have `ClientRequestToken` set as `token1`.
    #
    #   In the console, stack operations display the client request token on
    #   the Events tab. Stack operations that are initiated from the console
    #   use the token format *Console-StackOperation-ID*, which helps you
    #   easily identify the stack operation . For example, if you create a
    #   stack using the console, each stack event would be assigned the same
    #   token in the following format:
    #   `Console-CreateStack-7f59c3cf-00d2-40c7-b2ff-e75db0987002`.
    #
    # @option params [Boolean] :enable_termination_protection
    #   Whether to enable termination protection on the specified stack. If a
    #   user attempts to delete a stack with termination protection enabled,
    #   the operation fails and the stack remains unchanged. For more
    #   information, see [Protecting a Stack From Being Deleted][1] in the
    #   *CloudFormation User Guide*. Termination protection is deactivated on
    #   stacks by default.
    #
    #   For [nested stacks][2], termination protection is set on the root
    #   stack and can't be changed directly on the nested stack.

    #
    #   Any overridden parameter values will be applied to all stack instances
    #   in the specified accounts and Amazon Web Services Regions. When
    #   specifying parameters and their values, be aware of how CloudFormation
    #   sets parameter values during stack instance operations:
    #
    #   * To override the current value for a parameter, include the parameter
    #     and specify its value.
    #
    #   * To leave an overridden parameter set to its present value, include
    #     the parameter and specify `UsePreviousValue` as `true`. (You can't
    #     specify both a value and set `UsePreviousValue` to `true`.)
    #
    #   * To set an overridden parameter back to the value specified in the

    #     in the list.
    #
    #   * To leave all parameters set to their present values, don't specify
    #     this property at all.
    #

    #   The unique identifier for this stack set operation.
    #
    #   The operation ID also functions as an idempotency token, to ensure

    #
    #   If you don't specify an operation ID, the SDK generates one

    # @option params [String] :stack_id
    #   The stack ID you are importing into a new stack set. Specify the
    #   Amazon Resource Name (ARN) of the stack.
    #
    # @option params [Array<Types::Parameter>] :parameters
    #   The input parameters for the stack set template.
    #
    # @option params [Array<String>] :capabilities
    #   In some cases, you must explicitly acknowledge that your stack set
    #   template contains certain capabilities in order for CloudFormation to
    #   create the stack set and related stack instances.
    #
    #   * `CAPABILITY_IAM` and `CAPABILITY_NAMED_IAM`
    #
    #     Some stack templates might include resources that can affect
    #     permissions in your Amazon Web Services account; for example, by
    #     creating new Identity and Access Management (IAM) users. For those
    #     stack sets, you must explicitly acknowledge this by specifying one
    #     of these capabilities.
    #
    #     The following IAM resources require you to specify either the
    #     `CAPABILITY_IAM` or `CAPABILITY_NAMED_IAM` capability.
    #
    #     * If you have IAM resources, you can specify either capability.
    #
    #     * If you have IAM resources with custom names, you *must* specify
    #       `CAPABILITY_NAMED_IAM`.
    #
    #     * If you don't specify either of these capabilities, CloudFormation
    #       returns an `InsufficientCapabilities` error.
    #
    #     If your stack template contains these resources, we recommend that
    #     you review all permissions associated with them and edit their
    #     permissions if necessary.
    #
    #     * [ AWS::IAM::AccessKey][1]
    #
    #     * [ AWS::IAM::Group][2]
    #
    #     * [AWS::IAM::InstanceProfile][3]
    #
    #     * [ AWS::IAM::Policy][4]
    #
    #     * [ AWS::IAM::Role][5]
    #
    #     * [ AWS::IAM::User][6]
    #
    #     * [AWS::IAM::UserToGroupAddition][7]
    #
    #     For more information, see [Acknowledging IAM Resources in
    #     CloudFormation Templates][8].
    #
    #   * `CAPABILITY_AUTO_EXPAND`
    #
    #     Some templates reference macros. If your stack set template
    #     references one or more macros, you must create the stack set
    #     directly from the processed template, without first reviewing the
    #     resulting changes in a change set. To create the stack set directly,
    #     you must acknowledge this capability. For more information, see
    #     [Using CloudFormation Macros to Perform Custom Processing on
    #     Templates][9].
    #
    #     Stack sets with service-managed permissions don't currently support
    #     the use of macros in templates. (This includes the
    #     [AWS::Include][10] and [AWS::Serverless][11] transforms, which are
    #     macros hosted by CloudFormation.) Even if you specify this
    #     capability for a stack set with service-managed permissions, if you
    #     reference a macro in your template the stack set operation will
    #     fail.

    # @option params [Array<Types::Tag>] :tags
    #   The key-value pairs to associate with this stack set and the stacks
    #   created from it. CloudFormation also propagates these tags to
    #   supported resources that are created in the stacks. A maximum number
    #   of 50 tags can be specified.
    #
    #   If you specify tags as part of a `CreateStackSet` action,
    #   CloudFormation checks to see if you have the required IAM permission
    #   to tag resources. If you don't, the entire `CreateStackSet` action
    #   fails with an `access denied` error, and the stack set is not created.
    #
    # @option params [String] :administration_role_arn
    #   The Amazon Resource Name (ARN) of the IAM role to use to create this
    #   stack set.
    #
    #   Specify an IAM role only if you are using customized administrator
    #   roles to control which users or groups can manage specific stack sets
    #   within the same administrator account. For more information, see
    #   [Prerequisites: Granting Permissions for Stack Set Operations][1] in

    #
    # @option params [String] :execution_role_name
    #   The name of the IAM execution role to use to create the stack set. If
    #   you do not specify an execution role, CloudFormation uses the
    #   `AWSCloudFormationStackSetExecutionRole` role for the stack set
    #   operation.
    #
    #   Specify an IAM role only if you are using customized execution roles
    #   to control which stack resources users and groups can include in their
    #   stack sets.
    #
    # @option params [String] :permission_model
    #   Describes how the IAM roles required for stack set operations are
    #   created. By default, `SELF-MANAGED` is specified.
    #
    #   * With `self-managed` permissions, you must create the administrator
    #     and execution roles required to deploy to target accounts. For more
    #     information, see [Grant Self-Managed Stack Set Permissions][1].
    #
    #   * With `service-managed` permissions, StackSets automatically creates
    #     the IAM roles required to deploy to accounts managed by
    #     Organizations. For more information, see [Grant Service-Managed
    #     Stack Set Permissions][2].

    #
    # @option params [Types::AutoDeployment] :auto_deployment
    #   Describes whether StackSets automatically deploys to Organizations
    #   accounts that are added to the target organization or organizational
    #   unit (OU). Specify only if `PermissionModel` is `SERVICE_MANAGED`.
    #
    # @option params [String] :call_as
    #   \[Service-managed permissions\] Specifies whether you are acting as an
    #   account administrator in the organization's management account or as
    #   a delegated administrator in a member account.
    #
    #   By default, `SELF` is specified. Use `SELF` for stack sets with
    #   self-managed permissions.
    #
    #   * To create a stack set with service-managed permissions while signed
    #     in to the management account, specify `SELF`.
    #
    #   * To create a stack set with service-managed permissions while signed
    #     in to a delegated administrator account, specify `DELEGATED_ADMIN`.
    #
    #     Your Amazon Web Services account must be registered as a delegated
    #     admin in the management account. For more information, see [Register
    #     a delegated administrator][1] in the *CloudFormation User Guide*.
    #
    #   Stack sets with service-managed permissions are created in the

    #
    # @option params [String] :client_request_token
    #   A unique identifier for this `CreateStackSet` request. Specify this
    #   token if you plan to retry requests so that CloudFormation knows that
    #   you're not attempting to create another stack set with the same name.
    #   You might retry `CreateStackSet` requests to ensure that
    #   CloudFormation successfully received them.
    #
    #   If you don't specify an operation ID, the SDK generates one
    #   automatically.
    #
    #   **A suitable default value is auto-generated.** You should normally
    #   not need to pass this option.**

    # @option params [String] :type
    #   The kind of extension.
    #
    # @option params [required, String] :type_name
    #   The name of the extension being registered.
    #
    #   We suggest that extension names adhere to the following patterns:
    #
    #   * For resource types,
    #     *company\_or\_organization*\::*service*\::*type*.
    #
    #   * For modules,
    #     *company\_or\_organization*\::*service*\::*type*\::MODULE.
    #
    #   * For hooks, *MyCompany*\::*Testing*\::*MyTestHook*.
    #
    #   <note markdown="1"> The following organization namespaces are reserved and can't be used
    #   in your extension names:
    #
    #    * `Alexa`
    #
    #   * `AMZN`
    #
    #   * `Amazon`
    #
    #   * `AWS`
    #
    #   * `Custom`
    #
    #   * `Dev`
    #
    #    </note>
    #
    # @option params [required, String] :schema_handler_package
    #   A URL to the S3 bucket containing the extension project package that
    #   contains the necessary files for the extension you want to register.
    #
    #   For information about generating a schema handler package for the
    #   extension you want to register, see [submit][1] in the *CloudFormation
    #   CLI User Guide*.
    #
    #   <note markdown="1"> The user registering the extension must be able to access the package
    #   in the S3 bucket. That's, the user needs to have [GetObject][2]
    #   permissions for the schema handler package. For more information, see
    #   [Actions, Resources, and Condition Keys for Amazon S3][3] in the
    #   *Identity and Access Management User Guide*.

    # @option params [Types::LoggingConfig] :logging_config
    #   Specifies logging configuration information for an extension.
    #
    # @option params [String] :execution_role_arn
    #   The Amazon Resource Name (ARN) of the IAM role for CloudFormation to
    #   assume when invoking the extension.
    #
    #   For CloudFormation to assume the specified execution role, the role
    #   must contain a trust relationship with the CloudFormation service
    #   principle (`resources.cloudformation.amazonaws.com`). For more
    #   information about adding trust relationships, see [Modifying a role
    #   trust
    #   policy](IAM/latest/UserGuide/roles-managingrole-editing-console.html#roles-managingrole_edit-trust-policy)
    #   in the *Identity and Access Management User Guide*.
    #
    #   If your extension calls Amazon Web Services APIs in any of its
    #   handlers, you must create an <i> <a
    #   href="https://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles.html">IAM
    #   execution role</a> </i> that includes the necessary permissions to
    #   call those Amazon Web Services APIs, and provision that execution role
    #   in your account. When CloudFormation needs to invoke the resource type
    #   handler, CloudFormation assumes this execution role to create a
    #   temporary session token, which it then passes to the resource type
    #   handler, thereby supplying your resource type with the appropriate
    #   credentials.
    #
    # @option params [String] :client_request_token
    #   A unique identifier that acts as an idempotency key for this
    #   registration request. Specifying a client request token prevents
    #   CloudFormation from generating more than one version of an extension
    #   from the same registration request, even if the request is submitted

    #
    # @option params [Array<String>] :capabilities
    #   In some cases, you must explicitly acknowledge that your stack
    #   template contains certain capabilities in order for CloudFormation to
    #   update the stack.
    #
    #   * `CAPABILITY_IAM` and `CAPABILITY_NAMED_IAM`
    #
    #     Some stack templates might include resources that can affect
    #     permissions in your Amazon Web Services account; for example, by
    #     creating new Identity and Access Management (IAM) users. For those
    #     stacks, you must explicitly acknowledge this by specifying one of
    #     these capabilities.
    #
    #     The following IAM resources require you to specify either the
    #     `CAPABILITY_IAM` or `CAPABILITY_NAMED_IAM` capability.
    #
    #     * If you have IAM resources, you can specify either capability.
    #
    #     * If you have IAM resources with custom names, you *must* specify
    #       `CAPABILITY_NAMED_IAM`.
    #
    #     * If you don't specify either of these capabilities, CloudFormation
    #       returns an `InsufficientCapabilities` error.
    #
    #     If your stack template contains these resources, we suggest that you
    #     review all permissions associated with them and edit their
    #     permissions if necessary.
    #
    #     * [ AWS::IAM::AccessKey][1]
    #
    #     * [ AWS::IAM::Group][2]

    #
    #     For more information, see [Acknowledging IAM Resources in
    #     CloudFormation Templates][8].
    #
    #   * `CAPABILITY_AUTO_EXPAND`
    #
    #     Some template contain macros. Macros perform custom processing on
    #     templates; this can include simple actions like find-and-replace
    #     operations, all the way to extensive transformations of entire
    #     templates. Because of this, users typically create a change set from
    #     the processed template, so that they can review the changes
    #     resulting from the macros before actually updating the stack. If
    #     your stack template contains one or more macros, and you choose to
    #     update a stack directly from the processed template, without first
    #     reviewing the resulting changes in a change set, you must
    #     acknowledge this capability. This includes the [AWS::Include][9] and
    #     [AWS::Serverless][10] transforms, which are macros hosted by
    #     CloudFormation.
    #
    #     If you want to update a stack from a stack template that contains
    #     macros *and* nested stacks, you must update the stack directly from
    #     the template using this capability.
    #
    #     You should only update stacks directly from a stack template that
    #     contains macros if you know what processing the macro performs.
    #
    #      Each macro relies on an underlying Lambda service function for
    #     processing stack templates. Be aware that the Lambda function owner
    #     can update the function operation without CloudFormation being
    #     notified.
    #
    #     For more information, see [Using CloudFormation Macros to Perform
    #     Custom Processing on Templates][11].

    # @option params [Array<String>] :resource_types
    #   The template resource types that you have permissions to work with for
    #   this update stack action, such as `AWS::EC2::Instance`, `AWS::EC2::*`,
    #   or `Custom::MyCustomInstance`.
    #
    #   If the list of resource types doesn't include a resource that you're
    #   updating, the stack update fails. By default, CloudFormation grants
    #   permissions to all resource types. Identity and Access Management
    #   (IAM) uses this parameter for CloudFormation-specific condition keys
    #   in IAM policies. For more information, see [Controlling Access with
    #   Identity and Access Management][1].

    #
    #   [1]: https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-iam-template.html
    #
    # @option params [String] :role_arn
    #   The Amazon Resource Name (ARN) of an Identity and Access Management
    #   (IAM) role that CloudFormation assumes to update the stack.
    #   CloudFormation uses the role's credentials to make calls on your
    #   behalf. CloudFormation always uses this role for all future operations
    #   on the stack. Provided that users have permission to operate on the
    #   stack, CloudFormation uses this role even if the users don't have
    #   permission to pass it. Ensure that the role grants least privilege.
    #
    #   If you don't specify a value, CloudFormation uses the role that was
    #   previously associated with the stack. If no role is available,
    #   CloudFormation uses a temporary session that is generated from your
    #   user credentials.
    #
    # @option params [Types::RollbackConfiguration] :rollback_configuration
    #   The rollback triggers for CloudFormation to monitor during stack
    #   creation and updating operations, and for the specified monitoring
    #   period afterwards.
    #
    # @option params [String] :stack_policy_body
    #   Structure containing a new stack policy body. You can specify either
    #   the `StackPolicyBody` or the `StackPolicyURL` parameter, but not both.
    #
    #   You might update the stack policy, for example, in order to protect a
    #   new resource that you created during a stack update. If you don't
    #   specify a stack policy, the current policy that is associated with the
    #   stack is unchanged.
    #
    # @option params [String] :stack_policy_url
    #   Location of a file containing the updated stack policy. The URL must
    #   point to a policy (max size: 16KB) located in an S3 bucket in the same
    #   Region as the stack. You can specify either the `StackPolicyBody` or
    #   the `StackPolicyURL` parameter, but not both.
    #
    #   You might update the stack policy, for example, in order to protect a
    #   new resource that you created during a stack update. If you don't
    #   specify a stack policy, the current policy that is associated with the
    #   stack is unchanged.
    #
    # @option params [Array<String>] :notification_arns
    #   Amazon Simple Notification Service topic Amazon Resource Names (ARNs)
    #   that CloudFormation associates with the stack. Specify an empty list
    #   to remove all notification topics.
    #
    # @option params [Array<Types::Tag>] :tags
    #   Key-value pairs to associate with this stack. CloudFormation also
    #   propagates these tags to supported resources in the stack. You can
    #   specify a maximum number of 50 tags.
    #
    #   If you don't specify this parameter, CloudFormation doesn't modify
    #   the stack's tags. If you specify an empty value, CloudFormation
    #   removes all associated tags.
    #
    # @option params [Boolean] :disable_rollback
    #   Preserve the state of previously provisioned resources when an
    #   operation fails.
    #
    #   Default: `False`
    #
    # @option params [String] :client_request_token
    #   A unique identifier for this `UpdateStack` request. Specify this token
    #   if you plan to retry requests so that CloudFormation knows that
    #   you're not attempting to update a stack with the same name. You might
    #   retry `UpdateStack` requests to ensure that CloudFormation
    #   successfully received them.
    #
    #   All events triggered by a given stack operation are assigned the same
    #   client request token, which you can use to track operations. For
    #   example, if you execute a `CreateStack` operation with the token
    #   `token1`, then all the `StackEvents` generated by that operation will
    #   have `ClientRequestToken` set as `token1`.
    #
    #   In the console, stack operations display the client request token on
    #   the Events tab. Stack operations that are initiated from the console
    #   use the token format *Console-StackOperation-ID*, which helps you
    #   easily identify the stack operation . For example, if you create a
    #   stack using the console, each stack event would be assigned the same
    #   token in the following format:
    #   `Console-CreateStack-7f59c3cf-00d2-40c7-b2ff-e75db0987002`.

    #   * To override the current value for a parameter, include the parameter
    #     and specify its value.
    #
    #   * To leave an overridden parameter set to its present value, include
    #     the parameter and specify `UsePreviousValue` as `true`. (You can't
    #     specify both a value and set `UsePreviousValue` to `true`.)
    #
    #   * To set an overridden parameter back to the value specified in the
    #     stack set, specify a parameter list but don't include the parameter
    #     in the list.
    #
    #   * To leave all parameters set to their present values, don't specify
    #     this property at all.
    #
    #   During stack set updates, any parameter values overridden for a stack

    #
    # @option params [Array<Types::Parameter>] :parameters
    #   A list of input parameters for the stack set template.
    #
    # @option params [Array<String>] :capabilities
    #   In some cases, you must explicitly acknowledge that your stack
    #   template contains certain capabilities in order for CloudFormation to
    #   update the stack set and its associated stack instances.
    #
    #   * `CAPABILITY_IAM` and `CAPABILITY_NAMED_IAM`
    #
    #     Some stack templates might include resources that can affect
    #     permissions in your Amazon Web Services account; for example, by
    #     creating new Identity and Access Management (IAM) users. For those
    #     stacks sets, you must explicitly acknowledge this by specifying one
    #     of these capabilities.
    #
    #     The following IAM resources require you to specify either the
    #     `CAPABILITY_IAM` or `CAPABILITY_NAMED_IAM` capability.
    #
    #     * If you have IAM resources, you can specify either capability.
    #
    #     * If you have IAM resources with custom names, you *must* specify
    #       `CAPABILITY_NAMED_IAM`.
    #
    #     * If you don't specify either of these capabilities, CloudFormation
    #       returns an `InsufficientCapabilities` error.
    #
    #     If your stack template contains these resources, we recommend that
    #     you review all permissions associated with them and edit their
    #     permissions if necessary.
    #
    #     * [ AWS::IAM::AccessKey][1]
    #
    #     * [ AWS::IAM::Group][2]
    #
    #     * [ AWS::IAM::InstanceProfile][3]
    #
    #     * [ AWS::IAM::Policy][4]
    #
    #     * [ AWS::IAM::Role][5]
    #
    #     * [ AWS::IAM::User][6]
    #
    #     * [ AWS::IAM::UserToGroupAddition][7]
    #
    #     For more information, see [Acknowledging IAM Resources in
    #     CloudFormation Templates][8].
    #
    #   * `CAPABILITY_AUTO_EXPAND`
    #
    #     Some templates reference macros. If your stack set template
    #     references one or more macros, you must update the stack set
    #     directly from the processed template, without first reviewing the
    #     resulting changes in a change set. To update the stack set directly,
    #     you must acknowledge this capability. For more information, see
    #     [Using CloudFormation Macros to Perform Custom Processing on
    #     Templates][9].
    #
    #     Stack sets with service-managed permissions do not currently support
    #     the use of macros in templates. (This includes the
    #     [AWS::Include][10] and [AWS::Serverless][11] transforms, which are
    #     macros hosted by CloudFormation.) Even if you specify this
    #     capability for a stack set with service-managed permissions, if you
    #     reference a macro in your template the stack set operation will
    #     fail.

    #
    # @option params [Array<Types::Tag>] :tags
    #   The key-value pairs to associate with this stack set and the stacks
    #   created from it. CloudFormation also propagates these tags to
    #   supported resources that are created in the stacks. You can specify a
    #   maximum number of 50 tags.
    #
    #   If you specify tags for this parameter, those tags replace any list of
    #   tags that are currently associated with this stack set. This means:
    #
    #   * If you don't specify this parameter, CloudFormation doesn't modify
    #     the stack's tags.
    #
    #   * If you specify *any* tags using this parameter, you must specify
    #     *all* the tags that you want associated with this stack set, even
    #     tags you've specified before (for example, when creating the stack
    #     set or during a previous update of the stack set.). Any tags that
    #     you don't include in the updated list of tags are removed from the
    #     stack set, and therefore from the stacks and resources as well.
    #
    #   * If you specify an empty value, CloudFormation removes all currently
    #     associated tags.
    #
    #   If you specify new tags as part of an `UpdateStackSet` action,
    #   CloudFormation checks to see if you have the required IAM permission
    #   to tag resources. If you omit tags that are currently associated with
    #   the stack set from the list of tags you specify, CloudFormation
    #   assumes that you want to remove those tags from the stack set, and
    #   checks to see if you have permission to untag resources. If you don't
    #   have the necessary permission(s), the entire `UpdateStackSet` action
    #   fails with an `access denied` error, and the stack set is not updated.
    #
    # @option params [Types::StackSetOperationPreferences] :operation_preferences
    #   Preferences for how CloudFormation performs this stack set operation.
    #
    # @option params [String] :administration_role_arn
    #   The Amazon Resource Name (ARN) of the IAM role to use to update this
    #   stack set.
    #
    #   Specify an IAM role only if you are using customized administrator
    #   roles to control which users or groups can manage specific stack sets
    #   within the same administrator account. For more information, see
    #   [Granting Permissions for Stack Set Operations][1] in the
    #   *CloudFormation User Guide*.
    #
    #   If you specified a customized administrator role when you created the
    #   stack set, you must specify a customized administrator role, even if
    #   it is the same customized administrator role used with this stack set
    #   previously.
    #
    #
    #
    #   [1]: http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/stacksets-prereqs.html
    #
    # @option params [String] :execution_role_name
    #   The name of the IAM execution role to use to update the stack set. If
    #   you do not specify an execution role, CloudFormation uses the
    #   `AWSCloudFormationStackSetExecutionRole` role for the stack set
    #   operation.
    #
    #   Specify an IAM role only if you are using customized execution roles
    #   to control which stack resources users and groups can include in their
    #   stack sets.
    #
    #   If you specify a customized execution role, CloudFormation uses that
    #   role to update the stack. If you do not specify a customized execution
    #   role, CloudFormation performs the update using the role previously
    #   associated with the stack set, so long as you have permissions to
    #   perform operations on the stack set.
    #
    # @option params [Types::DeploymentTargets] :deployment_targets
    #   \[Service-managed permissions\] The Organizations accounts in which to
    #   update associated stack instances.
    #
    #   To update all the stack instances associated with this stack set, do
    #   not specify `DeploymentTargets` or `Regions`.
    #
    #   If the stack set update includes changes to the template (that is, if
    #   `TemplateBody` or `TemplateURL` is specified), or the `Parameters`,
    #   CloudFormation marks all stack instances with a status of `OUTDATED`
    #   prior to updating the stack instances in the specified accounts and
    #   Amazon Web Services Regions. If the stack set update doesn't include
    #   changes to the template or parameters, CloudFormation updates the
    #   stack instances in the specified accounts and Regions, while leaving
    #   all other stack instances with their existing stack instance status.
    #
    # @option params [String] :permission_model
    #   Describes how the IAM roles required for stack set operations are
    #   created. You cannot modify `PermissionModel` if there are stack
    #   instances associated with your stack set.
    #
    #   * With `self-managed` permissions, you must create the administrator
    #     and execution roles required to deploy to target accounts. For more
    #     information, see [Grant Self-Managed Stack Set Permissions][1].
    #
    #   * With `service-managed` permissions, StackSets automatically creates
    #     the IAM roles required to deploy to accounts managed by
    #     Organizations. For more information, see [Grant Service-Managed
    #     Stack Set Permissions][2].

    #
    # @option params [Types::AutoDeployment] :auto_deployment
    #   \[Service-managed permissions\] Describes whether StackSets
    #   automatically deploys to Organizations accounts that are added to a
    #   target organization or organizational unit (OU).
    #
    #   If you specify `AutoDeployment`, don't specify `DeploymentTargets` or
    #   `Regions`.
    #
    # @option params [String] :operation_id
    #   The unique ID for this stack set operation.
    #
    #   The operation ID also functions as an idempotency token, to ensure
    #   that CloudFormation performs the stack set operation only once, even
    #   if you retry the request multiple times. You might retry stack set
    #   operation requests to ensure that CloudFormation successfully received
    #   them.
    #
    #   If you don't specify an operation ID, CloudFormation generates one
    #   automatically.
    #
    #   Repeating this stack set operation with a new operation ID retries all
    #   stack instances whose status is `OUTDATED`.
    #
    #   **A suitable default value is auto-generated.** You should normally
    #   not need to pass this option.**
    #
    # @option params [Array<String>] :accounts
    #   \[Self-managed permissions\] The accounts in which to update
    #   associated stack instances. If you specify accounts, you must also
    #   specify the Amazon Web Services Regions in which to update stack set
    #   instances.
    #
    #   To update *all* the stack instances associated with this stack set,
    #   don't specify the `Accounts` or `Regions` properties.
    #
    #   If the stack set update includes changes to the template (that is, if
    #   the `TemplateBody` or `TemplateURL` properties are specified), or the
    #   `Parameters` property, CloudFormation marks all stack instances with a
    #   status of `OUTDATED` prior to updating the stack instances in the
    #   specified accounts and Amazon Web Services Regions. If the stack set
    #   update does not include changes to the template or parameters,
    #   CloudFormation updates the stack instances in the specified accounts
    #   and Amazon Web Services Regions, while leaving all other stack
    #   instances with their existing stack instance status.
    #
    # @option params [Array<String>] :regions
    #   The Amazon Web Services Regions in which to update associated stack
    #   instances. If you specify Regions, you must also specify accounts in
    #   which to update stack set instances.
    #
    #   To update *all* the stack instances associated with this stack set, do
    #   not specify the `Accounts` or `Regions` properties.
    #
    #   If the stack set update includes changes to the template (that is, if
    #   the `TemplateBody` or `TemplateURL` properties are specified), or the
    #   `Parameters` property, CloudFormation marks all stack instances with a
    #   status of `OUTDATED` prior to updating the stack instances in the
    #   specified accounts and Regions. If the stack set update does not
    #   include changes to the template or parameters, CloudFormation updates
    #   the stack instances in the specified accounts and Regions, while
    #   leaving all other stack instances with their existing stack instance
    #   status.
    #
    # @option params [String] :call_as
    #   \[Service-managed permissions\] Specifies whether you are acting as an
    #   account administrator in the organization's management account or as
    #   a delegated administrator in a member account.
    #
    #   By default, `SELF` is specified. Use `SELF` for stack sets with
    #   self-managed permissions.
    #
    #   * If you are signed in to the management account, specify `SELF`.
    #
    #   * If you are signed in to a delegated administrator account, specify
    #     `DELEGATED_ADMIN`.
    #
    #     Your Amazon Web Services account must be registered as a delegated
    #     administrator in the management account. For more information, see

    # Polls an API operation until a resource enters a desired state.
    #
    # ## Basic Usage
    #
    # A waiter will call an API operation until:
    #
    # * It is successful
    # * It enters a terminal state
    # * It makes the maximum number of attempts
    #
    # In between attempts, the waiter will sleep.
    #
    #     # polls in a loop, sleeping between attempts
    #     client.wait_until(waiter_name, params)
    #
    # ## Configuration
    #
    # You can configure the maximum number of polling attempts, and the
    # delay (in seconds) between each polling attempt. You can pass
    # configuration as the final arguments hash.
    #
    #     # poll for ~25 seconds
    #     client.wait_until(waiter_name, params, {
    #       max_attempts: 5,
    #       delay: 5,
    #     })
    #
    # ## Callbacks
    #
    # You can be notified before each polling attempt and before each
    # delay. If you throw `:success` or `:failure` from these callbacks,
    # it will terminate the waiter.
    #
    #     started_at = Time.now
    #     client.wait_until(waiter_name, params, {
    #
    #       # disable max attempts
    #       max_attempts: nil,
    #
    #       # poll for 1 hour, instead of a number of attempts
    #       before_wait: -> (attempts, response) do
    #         throw :failure if Time.now - started_at > 3600
    #       end
    #     })
    #
    # ## Handling Errors
    #
    # When a waiter is unsuccessful, it will raise an error.
    # All of the failure errors extend from
    # {Aws::Waiters::Errors::WaiterFailed}.
    #
    #     begin
    #       client.wait_until(...)
    #     rescue Aws::Waiters::Errors::WaiterFailed
    #       # resource did not enter the desired state in time
    #     end
