Yes, the receipt contains the signiture and your assertion that you checked the signiture against the content, verifying the message content has arrived exactly as sent. This allows your trading partner to take business action due to shared understanding (possibly contractual) of the agreed commitment for completing the associated business action.
I know that is a mouthful, but it is all about taking friction out of the supply chain, and optimizing the execution of the collaborative process.

Does this mean a receipt could contain the MD5 signiture of the message to prove we got what was sent?

I suppose you could put the receipt ack information into the response and not need a response, however JUST HAVING a response does NOT satisfy legal requirements on the content of the request nor proof of receipt of the request. Most legal disputes that attempt to say "specific action should have been taken" MUST show that the request (and its content) is exactly what was received.
The question is not timing, not "did they get a request", but more EXACTLY WHAT was received and EXACTLY WHEN was it received and with proof.

This is not a recommendation but a question.
Lars (and Hima), this was your original issue. Any comments? Thanks.
 We have seen related recommendations in the messaging arena.
