	// snapshot. This parameter is not case sensitive. Constraints:
	//   - Must contain from 1 to 63 letters, numbers, or hyphens.
	//   - The first character must be a letter.

	// The KMS key ID for an encrypted cluster snapshot. The KMS key ID is the Amazon
	// Resource Name (ARN), KMS key identifier, or the KMS key alias for the KMS
	// encryption key. If you copy an encrypted cluster snapshot from your Amazon Web
	// Services account, you can specify a value for KmsKeyId to encrypt the copy with
	// a new KMS encryption key. If you don't specify a value for KmsKeyId , then the
	// copy of the cluster snapshot is encrypted with the same KMS key as the source
	// cluster snapshot. If you copy an encrypted cluster snapshot that is shared from
	// another Amazon Web Services account, then you must specify a value for KmsKeyId
	// . To copy an encrypted cluster snapshot to another Amazon Web Services Region,
	// set KmsKeyId to the KMS key ID that you want to use to encrypt the copy of the
	// cluster snapshot in the destination Region. KMS encryption keys are specific to
	// the Amazon Web Services Region that they are created in, and you can't use
	// encryption keys from one Amazon Web Services Region in another Amazon Web
	// Services Region. If you copy an unencrypted cluster snapshot and specify a value
	// for the KmsKeyId parameter, an error is returned.
	KmsKeyId *string

	// The URL that contains a Signature Version 4 signed request for the
	// CopyDBClusterSnapshot API action in the Amazon Web Services Region that contains
	// the source cluster snapshot to copy. You must use the PreSignedUrl parameter
	// when copying a cluster snapshot from another Amazon Web Services Region. If you
	// are using an Amazon Web Services SDK tool or the CLI, you can specify
	// SourceRegion (or --source-region for the CLI) instead of specifying PreSignedUrl
	// manually. Specifying SourceRegion autogenerates a pre-signed URL that is a
	// valid request for the operation that can be executed in the source Amazon Web
	// Services Region. The presigned URL must be a valid request for the
	// CopyDBClusterSnapshot API action that can be executed in the source Amazon Web
	// Services Region that contains the cluster snapshot to be copied. The presigned
	// URL request must contain the following parameter values:
	//   - SourceRegion - The ID of the region that contains the snapshot to be copied.
	//   - SourceDBClusterSnapshotIdentifier - The identifier for the the encrypted
	//   cluster snapshot to be copied. This identifier must be in the Amazon Resource
	//   Name (ARN) format for the source Amazon Web Services Region. For example, if you
	//   are copying an encrypted cluster snapshot from the us-east-1 Amazon Web Services
	//   Region, then your SourceDBClusterSnapshotIdentifier looks something like the
	//   following:
	//   arn:aws:rds:us-east-1:12345678012:sample-cluster:sample-cluster-snapshot .
	//   - TargetDBClusterSnapshotIdentifier - The identifier for the new cluster
	//   snapshot to be created. This parameter isn't case sensitive.
	PreSignedUrl *string
