    IMO, if you are doing a one-way asynch message pattern over HTTP, with asynch
    ack on a separate channel in the reverse direction, then the HTTP response for the
    original POST should be a 202 Accepted. That response should be returned WITHOUT
    any processing (MSH or application-level) of the message, which is what 202 implies.

    So, from the receiving end, it would be:

    1) receive message
    2) send 202 response
    3) dispatch message to MSH for processing and eventual dispatch to application.
