    :type KeyId: string
    :param KeyId: [REQUIRED]
            A unique identifier for the CMK whose tags you are listing. You can use the unique key ID or the Amazon Resource Name (ARN) of the CMK. Examples:
            Unique key ID: 1234abcd-12ab-34cd-56ef-1234567890ab
            Key ARN: arn:aws:kms:us-east-2:111122223333:key/1234abcd-12ab-34cd-56ef-1234567890ab
            

    :type Limit: integer
    :param Limit: Use this parameter to specify the maximum number of items to return. When this value is present, AWS KMS does not return more than the specified number of items, but it might return fewer.
            This value is optional. If you include a value, it must be between 1 and 50, inclusive. If you do not include a value, it defaults to 50.
            

    :type Marker: string
    :param Marker: Use this parameter in a subsequent request after you receive a response with truncated results. Set it to the value of NextMarker from the truncated response you just received.
            Do not attempt to construct this value. Use only the value of NextMarker from the truncated response you just received.
