The
verification of the correct sequencing should be done by the middleware (the

"I can understand that at a lower level TRP service, there's something dealing with 'message counting' but I'm not aware that something like this info finds it's way up the stack so the business app's can also do their counting; which does sound like redundant but it is the way of the world and as such it's not going to stop. "
In our "simple negotiation pattern" test, we also noted that messages need to be able to cross reference each other, and sought confirmation of some kind of unique message ID.
Good questions. I don't know the answer. Can we do that? Goes on my list for tomorrow's metamodel meeting. Jamie
