Subject: RE: [ebxml-msg] Semantics of AS4 Receipt

Our current implementation sends a receipt (currently only for receipt
awareness) only after the "next step" is taken i.e. placed in a queue.
The only guarantee is that the next step taken was successful. What
happens after that is not.

Agreed with Dale. I kind of see the AS4 MSH as DCE (data communications
equipment) transparent to associated business processes.

was that we not proceed beyond secured, acknowledgement of receipt (and,
when security features are OK, an indication that the next processing
step was engaged). I am uncertain about "successful transfer" - the MSH
did its step in "processing," but whether the next processing step was
successful is not assured. (For example, the payload might be placed on
a queue, but whether the payload was taken off the queue is an open
question as far as the signal is concerned.)

should go there with data exchange protocols. That does not prevent
embedding data exchange protocols in richer coordination protocols that
might add on various notification services. But I would not want to get
into these additions within AS4. I think the additional protocols should
be developed as applications of existing IETF protocols, maybe as an
EDIINT-NG or B2B-NG interest group. I don't think it should be an OASIS
effort. Just my opinion (or using the new catch phrase), just sayin']
