Receive SQS Message with UserMessageAttributes

[jtdawso]

@aristidb Is there an example of getting a message with its UserMessageAttributes?

I have a message in SQS with UserMessageAttributes, if I have the following ReceiveMessage:
(delay, MessageAttributes, #messages, UserMessageAttributeName, queueName, wait time in seconds)
ReceiveMessage (Just 2) [] (Just 10) [] name (Just 20)
I am able to recieve the messages but without any UserMessageAttributes or MessageAttributes. When I do the following:

ReceiveMessage (Just 2) [MessageAll] (Just 10) [] name (Just 20)
I get all the message Attributes as expected, however if I put "All" or ".*" or the attribute that I am looking for in the UserMessageAttribute list, I get the following error:

XmlException {xmlErrorMessage = \"Missing DataType\"}"
