	// CloudFormation always converts a YAML policy to JSON format before submitting it
	// to IAM.
	//
	// The maximum length of the policy document that you can pass in this operation,
	// including whitespace, is listed below. To view the maximum character counts of a

	//
	// To learn more about JSON policy grammar, see [Grammar of the IAM JSON policy language] in the IAM User Guide.
	//
	// The [regex pattern] used to validate this parameter is a string of characters consisting of
	// the following:
	//
	//   - Any printable ASCII character ranging from the space character ( \u0020 )
	//   through the end of the ASCII character range
	//
	//   - The printable characters in the Basic Latin and Latin-1 Supplement
	//   character set (through \u00FF )

	PolicyDocument *string

	// The friendly name of the policy.
	//
	// IAM user, group, role, and policy names must be unique within the account.
	// Names are not distinguished by case. For example, you cannot create resources

	// For more information about paths, see [IAM identifiers] in the IAM User Guide.

	//
	// This parameter allows (through its [regex pattern]) a string of characters consisting of

	// \u0021 ) through the DEL character ( \u007F ), including most punctuation
	// characters, digits, and upper and lowercased letters.

	// You cannot use an asterisk (*) in the path name.
