	//   - If you are signed in to the management account, specify SELF .

	// In some cases, you must explicitly acknowledge that your stack template

	//   - 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

	//   Custom Processing on Templates (https://docs.aws.amazon.com/AWSCloudFormation/template-macros.html)
	//   . Stack sets with service-managed permissions do not currently support the use
	//   of macros in templates. (This includes the AWS::Include (https://docs.aws.amazon.com/AWSCloudFormation/create-reusable-transform-function-snippets-and-add-to-your-template-with-aws-include-transform.html)

	Capabilities []types.Capability

	// [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

	// instances in the specified accounts and Regions, while leaving all other stack
	// instances with their existing stack instance status.
	DeploymentTargets *types.DeploymentTargets

	// A brief description of updates that you are making.
	Description *string

	// 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.
	ExecutionRoleName *string

	// Describes whether StackSets performs non-conflicting operations concurrently
	// and queues conflicting operations.
	ManagedExecution *types.ManagedExecution

	// 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 .
	OperationId *string

	// Preferences for how CloudFormation performs this stack set operation.
	OperationPreferences *types.StackSetOperationPreferences

	// A list of input parameters for the stack set template.
	Parameters []types.Parameter

	// 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 (https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/stacksets-prereqs-self-managed.html)
	//   .
	//   - 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 (https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/stacksets-prereqs-service-managed.html)
	//   .
	PermissionModel types.PermissionModels

	// 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.
	Regions []string

	// 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.
	Tags []types.Tag

	// The structure that contains the template body, with a minimum length of 1 byte
	// and a maximum length of 51,200 bytes. For more information, see Template Anatomy (https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/template-anatomy.html)
	// in the CloudFormation User Guide. Conditional: You must specify only one of the
	// following parameters: TemplateBody or TemplateURL —or set UsePreviousTemplate
	// to true.
	TemplateBody *string

	// The location of the file that contains the template body. The URL must point to
	// a template (maximum size: 460,800 bytes) that is located in an Amazon S3 bucket
	// or a Systems Manager document. For more information, see Template Anatomy (https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/template-anatomy.html)
