	// In some cases, you must explicitly acknowledge that your stack template contains
	// certain capabilities in order for AWS CloudFormation to create the stack.
	//
	//    * CAPABILITY_IAM and CAPABILITY_NAMED_IAM Some stack templates might include
	//    resources that can affect permissions in your AWS account; for example,
	//    by creating new AWS 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, AWS 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 (https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-iam-accesskey.html)

	//    Templates (http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-iam-template.html#capabilities).
	//
	//    * 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 (http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/create-reusable-transform-function-snippets-and-add-to-your-template-with-aws-include-transform.html)
	//    and AWS::Serverless (http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/transform-aws-serverless.html)
	//    transforms, which are macros hosted by AWS CloudFormation. This capacity
	//    does not apply to creating change sets, and specifying it when creating
	//    change sets has no effect. Also, change sets do not currently support
	//    nested stacks. 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. For more information on macros, see Using
	//    AWS CloudFormation Macros to Perform Custom Processing on Templates (http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/template-macros.html).

// Creates a list of changes that will be applied to a stack so that you can
// review the changes before executing them. You can create a change set for
// a stack that doesn't exist or an existing stack. If you create a change set
// for a stack that doesn't exist, the change set shows all of the resources
// that AWS CloudFormation will create. If you create a change set for an existing
// stack, AWS CloudFormation compares the stack's information with the information
// that you submit in the change set and lists the differences. Use change sets
// to understand which resources AWS CloudFormation will create or change, and
// how it will change resources in an existing stack, before you create or update
// a stack.
//
// To create a change set for a stack that doesn't exist, for the ChangeSetType
// parameter, specify CREATE. To create a change set for an existing stack,
// specify UPDATE for the ChangeSetType parameter. To create a change set for
// an import operation, specify IMPORT for the ChangeSetType parameter. After
// the CreateChangeSet call successfully completes, AWS CloudFormation starts
// creating the change set. To check the status of the change set or to review
// it, use the DescribeChangeSet action.
//
// When you are satisfied with the changes the change set will make, execute
// the change set by using the ExecuteChangeSet action. AWS CloudFormation doesn't
// make changes until you execute the change set.
