-- Delivers a message to the specified queue. With Amazon SQS, you now have
-- the ability to send large payload messages that are up to 256KB (262,144
-- bytes) in size. To send large payloads, you must use an AWS SDK that
-- supports SigV4 signing. To verify whether SigV4 is supported for an AWS
-- SDK, check the SDK release notes.
--
-- The following list shows the characters (in Unicode) allowed in your
-- message, according to the W3C XML specification. For more information,
-- go to <http://www.w3.org/TR/REC-xml/#charsets> If you send any
-- characters not included in the list, your request will be rejected.
