	// see the W3C specification for characters (http://www.w3.org/TR/REC-xml/#charsets).
	//
	// MessageBody is a required field
	MessageBody *string `type:"string" required:"true"`

	// This parameter applies only to FIFO (first-in-first-out) queues.
	//
	// The token used for deduplication of sent messages. If a message with a particular
	// MessageDeduplicationId is sent successfully, any messages sent with the same
	// MessageDeduplicationId are accepted successfully but aren't delivered during
	// the 5-minute deduplication interval. For more information, see Exactly-Once
	// Processing (https://docs.aws.amazon.com/AWSSimpleQueueService/latest/SQSDeveloperGuide/FIFO-queues.html#FIFO-queues-exactly-once-processing)
	// in the Amazon Simple Queue Service Developer Guide.
	//
	//    * Every message must have a unique MessageDeduplicationId, You may provide
	//    a MessageDeduplicationId explicitly. If you aren't able to provide a MessageDeduplicationId
	//    and you enable ContentBasedDeduplication for your queue, Amazon SQS uses
	//    a SHA-256 hash to generate the MessageDeduplicationId using the body of
	//    the message (but not the attributes of the message). If you don't provide
	//    a MessageDeduplicationId and the queue doesn't have ContentBasedDeduplication
	//    set, the action fails with an error. If the queue has ContentBasedDeduplication
	//    set, your MessageDeduplicationId overrides the generated one.
	//
	//    * When ContentBasedDeduplication is in effect, messages with identical
	//    content sent within the deduplication interval are treated as duplicates
	//    and only one copy of the message is delivered.
	//
	//    * If you send one message with ContentBasedDeduplication enabled and then
	//    another message with a MessageDeduplicationId that is the same as the
	//    one generated for the first MessageDeduplicationId, the two messages are
	//    treated as duplicates and only one copy of the message is delivered.
	//
	// The MessageDeduplicationId is available to the consumer of the message (this
	// can be useful for troubleshooting delivery issues).
	//
	// If a message is sent successfully but the acknowledgement is lost and the
	// message is resent with the same MessageDeduplicationId after the deduplication
	// interval, Amazon SQS can't detect duplicate messages.
	//
	// Amazon SQS continues to keep track of the message deduplication ID even after
	// the message is received and deleted.
	//
	// The maximum length of MessageDeduplicationId is 128 characters. MessageDeduplicationId
	// can contain alphanumeric characters (a-z, A-Z, 0-9) and punctuation (!"#$%&'()*+,-./:;<=>?@[\]^_`{|}~).

	// This parameter applies only to FIFO (first-in-first-out) queues.
	//
	// The tag that specifies that a message belongs to a specific message group.
	// Messages that belong to the same message group are processed in a FIFO manner
	// (however, messages in different message groups might be processed out of
	// order). To interleave multiple ordered streams within a single queue, use
	// MessageGroupId values (for example, session data for multiple users). In
	// this scenario, multiple consumers can process the queue, but the session
	// data of each user is processed in a FIFO fashion.
	//
	//    * You must associate a non-empty MessageGroupId with a message. If you
	//    don't provide a MessageGroupId, the action fails.
	//
	//    * ReceiveMessage might return messages with multiple MessageGroupId values.
	//    For each MessageGroupId, the messages are sorted by time sent. The caller
	//    can't specify a MessageGroupId.
