    # Structure that contains the results of the account gate function which
    # CloudFormation invokes, if present, before proceeding with a stack set
    # operation in an account and Region.
    #
    # For each account and Region, CloudFormation lets you specify a Lambda
    # function that encapsulates any requirements that must be met before
    # CloudFormation can proceed with a stack set operation in that account
    # and Region. CloudFormation invokes the function each time a stack set
    # operation is requested for that account and Region; if the function
    # returns `FAILED`, CloudFormation cancels the operation in that account
    # and Region, and sets the stack set operation result status for that
    # account and Region to `FAILED`.
    #
    # For more information, see [Configuring a target account gate][1].

    # @!attribute [rw] status
    #   The status of the account gate function.
    #
    #   * `SUCCEEDED`: The account gate function has determined that the
    #     account and Region passes any requirements for a stack set
    #     operation to occur. CloudFormation proceeds with the stack
    #     operation in that account and Region.
    #
    #   * `FAILED`: The account gate function has determined that the
    #     account and Region doesn't meet the requirements for a stack set
    #     operation to occur. CloudFormation cancels the stack set operation
    #     in that account and Region, and sets the stack set operation
    #     result status for that account and Region to `FAILED`.
    #
    #   * `SKIPPED`: CloudFormation has skipped calling the account gate
    #     function for this account and Region, for one of the following
    #     reasons:
    #
    #     * An account gate function hasn't been specified for the account
    #       and Region. CloudFormation proceeds with the stack set operation
    #       in this account and Region.
    #
    #     * The `AWSCloudFormationStackSetExecutionRole` of the stack set
    #       administration account lacks permissions to invoke the function.
    #       CloudFormation proceeds with the stack set operation in this
    #       account and Region.
    #
    #     * Either no action is necessary, or no action is possible, on the
    #       stack. CloudFormation skips the stack set operation in this
    #       account and Region.

    #   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 permission.
    #
    #   If you don't specify a value, CloudFormation uses the role that was
    #   previously associated with the stack. If no role is available,

    # @!attribute [rw] 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
    #   rollback operation with nested stacks, see [Using ResourcesToSkip to
    #   recover a nested stacks hierarchy][2].

    # @!attribute [rw] capabilities
    #   In some cases, you must explicitly acknowledge that your stack

    #   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.

    #     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.
    #
    #     <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.
    #

    # @!attribute [rw] 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.

    #
    #   * `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].

    #   (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,

    #   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

    #
    #   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:

    #
    #     * If you don't specify either of these capabilities,
    #       CloudFormation returns an `InsufficientCapabilities` error.

    #     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.

    #
    #   * `ResourceAttribute` entities are `Fn::GetAtt` intrinsic functions

    #     "MyEC2InstanceResource", "PublicDnsName" ] \}`.
    #

    #     to the template.
    #
    #   * `Automatic` entities are `AWS::CloudFormation::Stack` resource
    #     types, which are also known as nested stacks. If you made no
    #     changes to the `AWS::CloudFormation::Stack` resource,
    #     CloudFormation sets the `ChangeSource` to `Automatic` because the

    #   The triggers to monitor during stack creation or update actions.
    #
    #   By default, CloudFormation saves the rollback triggers specified for
    #   a stack and applies them to any subsequent update operations for the
    #   stack, unless you specify otherwise. If you do specify rollback
    #   triggers for this parameter, those triggers replace any list of
    #   triggers previously specified for the stack. This means:
    #
    #   * To use the rollback triggers previously specified for this stack,
    #     if any, don't specify this parameter.
    #
    #   * To specify new or updated rollback triggers, you must specify
    #     *all* the triggers that you want used for this stack, even
    #     triggers you've specified before (for example, when creating the
    #     stack or during a previous stack update). Any triggers that you
    #     don't include in the updated list of triggers are no longer
    #     applied to the stack.
    #
    #   * To remove all currently specified triggers, specify an empty list
    #     for this parameter.
    #
    #   If a specified trigger is missing, the entire stack operation fails
    #   and is rolled back.
    #   @return [Array<Types::RollbackTrigger>]
    #
    # @!attribute [rw] monitoring_time_in_minutes
    #   The amount of time, in minutes, during which CloudFormation should
    #   monitor all the rollback triggers after the stack creation or update
    #   operation deploys all necessary resources.
    #
    #   The default is 0 minutes.
    #
    #   If you specify a monitoring period but don't specify any rollback
    #   triggers, CloudFormation still waits the specified period of time
    #   before cleaning up old resources after update operations. You can
    #   use this monitoring period to perform any manual stack validation
    #   desired, and manually cancel the stack creation or update (using
    #   [CancelUpdateStack][1], for example) as necessary.
    #
    #   If you specify 0 for this parameter, CloudFormation still monitors
    #   the specified rollback triggers during stack creation and update
    #   operations. Then, for update operations, it begins disposing of old
    #   resources immediately once the operation completes.

    #   In some cases, you must explicitly acknowledge that your stack

    #   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.

    #     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].

    #   When specifying parameters and their values, be aware of how
    #   CloudFormation sets parameter values during stack instance update
    #   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
    #     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 instance aren't updated, but retain their overridden value.
    #
    #   You can only override the parameter *values* that are specified in
    #   the stack set; to add or delete a parameter itself, use
    #   `UpdateStackSet` to update the stack set template. If you add a
    #   parameter to a template, before you can override the parameter value
    #   specified in the stack set you must first use [UpdateStackSet][1] to
    #   update all stack instances with the updated template and parameter

    #   In some cases, you must explicitly acknowledge that your stack

    #   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.

    #
    #   * `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.
