Re: T2 PLEAE READ - Suggested solution to RM Issues

Dan,

I agree almost completely.

We certainly can't get into specifying the messaging protocol between B and
C if that interaction is not according to ebXML.  However, if we expect
reliable messaging to work between A and D while B and C are using a
different protocol, we still have to say something about what is expected
of B and C and their interaction in order to support reliable messaging
between A and D.  To repeat the example from IBM's HTTPR that I have
already given a couple of times: "It is assumed that intermediaries store
and forward messages reliably." If we do not state the assumptions on the
intermediaries, all bets are off as to whether reliable messaging works
across the intermediaries.

Regards,
Marty

It's not a contradiction.  Both scenarios are plausible.

OK, both are plausible, but I didn't see where you switched between
one and the other, so I'm having trouble following you.  But I think
we have to agree, when we design ebXML MS, whether what we're
designing is the IM-to-IM protocol, or not.

*If* we want to allow a scenario of A - B - C - D where B and C are
IM's and the B and C can use whatever protocol they want, *then* I
don't think we should characterize ebXML MS as the IM-to-IM protocol.
Rather, ebXML MS defines the A - B communication (when it's talking
about HTTP addresses), and the A - D communication (when it's talking
about service/action), but not the B - C communication.
