	// provided in CallerArn. This parameter is required only if you specify a resource-based
	// policy and account that owns the resource is different from the account that
	// owns the simulated calling user CallerArn.
	//
	// The ARN for an account uses the following syntax: arn:aws:iam::AWS-account-ID:root.
