    # Information about a load balancer attribute.
    #
    # @!attribute [rw] key
    #   The name of the attribute.
    #
    #   The following attributes are supported by all load balancers:
    #
    #   * `deletion_protection.enabled` - Indicates whether deletion
    #     protection is enabled. The value is `true` or `false`. The default
    #     is `false`.
    #
    #   * `load_balancing.cross_zone.enabled` - Indicates whether cross-zone
    #     load balancing is enabled. The possible values are `true` and
    #     `false`. The default for Network Load Balancers and Gateway Load
    #     Balancers is `false`. The default for Application Load Balancers
    #     is `true`, and can't be changed.
    #
    #   The following attributes are supported by both Application Load
    #   Balancers and Network Load Balancers:
    #
    #   * `access_logs.s3.enabled` - Indicates whether access logs are
    #     enabled. The value is `true` or `false`. The default is `false`.
    #
    #   * `access_logs.s3.bucket` - The name of the S3 bucket for the access
    #     logs. This attribute is required if access logs are enabled. The
    #     bucket must exist in the same region as the load balancer and have
    #     a bucket policy that grants Elastic Load Balancing permissions to
    #     write to the bucket.
    #
    #   * `access_logs.s3.prefix` - The prefix for the location in the S3
    #     bucket for the access logs.
    #
    #   * `ipv6.deny_all_igw_traffic` - Blocks internet gateway (IGW) access
    #     to the load balancer. It is set to `false` for internet-facing
    #     load balancers and `true` for internal load balancers, preventing
    #     unintended access to your internal load balancer through an
    #     internet gateway.
    #
    #   The following attributes are supported by only Application Load
    #   Balancers:
    #
    #   * `idle_timeout.timeout_seconds` - The idle timeout value, in
    #     seconds. The valid range is 1-4000 seconds. The default is 60
    #     seconds.
    #
    #   * `client_keep_alive.seconds` - The client keep alive value, in
    #     seconds. The valid range is 60-604800 seconds. The default is 3600
    #     seconds.
    #
    #   * `connection_logs.s3.enabled` - Indicates whether connection logs
    #     are enabled. The value is `true` or `false`. The default is
    #     `false`.
    #
    #   * `connection_logs.s3.bucket` - The name of the S3 bucket for the
    #     connection logs. This attribute is required if connection logs are
    #     enabled. The bucket must exist in the same region as the load
    #     balancer and have a bucket policy that grants Elastic Load
    #     Balancing permissions to write to the bucket.
    #
    #   * `connection_logs.s3.prefix` - The prefix for the location in the
    #     S3 bucket for the connection logs.
    #
    #   * `routing.http.desync_mitigation_mode` - Determines how the load
    #     balancer handles requests that might pose a security risk to your
    #     application. The possible values are `monitor`, `defensive`, and
    #     `strictest`. The default is `defensive`.
    #
    #   * `routing.http.drop_invalid_header_fields.enabled` - Indicates
    #     whether HTTP headers with invalid header fields are removed by the
    #     load balancer (`true`) or routed to targets (`false`). The default
    #     is `false`.
    #
    #   * `routing.http.preserve_host_header.enabled` - Indicates whether
    #     the Application Load Balancer should preserve the `Host` header in
    #     the HTTP request and send it to the target without any change. The
    #     possible values are `true` and `false`. The default is `false`.
    #
    #   * `routing.http.x_amzn_tls_version_and_cipher_suite.enabled` -
    #     Indicates whether the two headers (`x-amzn-tls-version` and
    #     `x-amzn-tls-cipher-suite`), which contain information about the
    #     negotiated TLS version and cipher suite, are added to the client
    #     request before sending it to the target. The `x-amzn-tls-version`
    #     header has information about the TLS protocol version negotiated
    #     with the client, and the `x-amzn-tls-cipher-suite` header has
    #     information about the cipher suite negotiated with the client.
    #     Both headers are in OpenSSL format. The possible values for the
    #     attribute are `true` and `false`. The default is `false`.
    #
    #   * `routing.http.xff_client_port.enabled` - Indicates whether the
    #     `X-Forwarded-For` header should preserve the source port that the
    #     client used to connect to the load balancer. The possible values
    #     are `true` and `false`. The default is `false`.
    #
    #   * `routing.http.xff_header_processing.mode` - Enables you to modify,
    #     preserve, or remove the `X-Forwarded-For` header in the HTTP
    #     request before the Application Load Balancer sends the request to
    #     the target. The possible values are `append`, `preserve`, and
    #     `remove`. The default is `append`.
    #
    #     * If the value is `append`, the Application Load Balancer adds the
    #       client IP address (of the last hop) to the `X-Forwarded-For`
    #       header in the HTTP request before it sends it to targets.
    #
    #     * If the value is `preserve` the Application Load Balancer
    #       preserves the `X-Forwarded-For` header in the HTTP request, and
    #       sends it to targets without any change.
    #
    #     * If the value is `remove`, the Application Load Balancer removes
    #       the `X-Forwarded-For` header in the HTTP request before it sends
    #       it to targets.
    #
    #   * `routing.http2.enabled` - Indicates whether HTTP/2 is enabled. The
    #     possible values are `true` and `false`. The default is `true`.
    #     Elastic Load Balancing requires that message header names contain
    #     only alphanumeric characters and hyphens.
    #
    #   * `waf.fail_open.enabled` - Indicates whether to allow a WAF-enabled
    #     load balancer to route requests to targets if it is unable to
    #     forward the request to Amazon Web Services WAF. The possible
    #     values are `true` and `false`. The default is `false`.
    #
    #   The following attributes are supported by only Network Load
    #   Balancers:
    #
    #   * `dns_record.client_routing_policy` - Indicates how traffic is
    #     distributed among the load balancer Availability Zones. The
    #     possible values are `availability_zone_affinity` with 100 percent
    #     zonal affinity, `partial_availability_zone_affinity` with 85
    #     percent zonal affinity, and `any_availability_zone` with 0 percent
    #     zonal affinity.
    #
    #   * `zonal_shift.config.enabled` - Indicates whether zonal shift is
    #     enabled. The possible values are `true` and `false`. The default
    #     is `false`.

    #
    #   * `target_health_state.unhealthy.draining_interval_seconds` - The
    #     amount of time for Elastic Load Balancing to wait before changing
    #     the state of an unhealthy target from `unhealthy.draining` to

    #     Load Balancer handles existing flows when a target is
    #     deregistered. The possible values are `rebalance` and
    #     `no_rebalance`. The default is `no_rebalance`. The two attributes
    #     (`target_failover.on_deregistration` and
    #     `target_failover.on_unhealthy`) can't be set independently. The
    #     value you set for both attributes must be the same.
    #
    #   * `target_failover.on_unhealthy` - Indicates how the Gateway Load
    #     Balancer handles existing flows when a target is unhealthy. The
    #     possible values are `rebalance` and `no_rebalance`. The default is
