Subject: Re: Special note for CPP members
Matthew, *Without focusing on the schedule and logistics*, It is not true that "interoperability will be nearly impossible in the business process stack.". Business/consortiums can still agree on what specific BP *are*, and the service interfaces, represent them in consistent rendering, and conduct business even if with manually typing in the runtime configuration file (CPA), but without dynamic fully automatic interoperable discovery and agreement formulation. These are important steps in themselves -consistent BP representations and using them to do business with other ebXML infrastructure components, even if you know your business partners already. The ToDo list is a good idea. Marty -please post to stc list. thanks.

Do you expect CPAs to be negotiated by hand until ebXML v2? It is not enough to tout transport and registry interoperability. Users and vendors need to fill in the CPA blank with a negotiation protocol, which if followed by implementors will result in fewer unaccepted CPAs. Having said that, I understand that you guys are under the gun for time. Would it not be possible to add a discussion about this topic to a public TODO list, so that interested parties will see that the problem is acknowledged? Cheers, Matthew MacKenzie XMLGlobal <<| message from: "Scott Hinkelman" <srh@us.ibm.com> |>> There is consensus in the TP team not to define a negotiation protocol.
