Subject: RE: [ebxml-msg] Addition to Gateway Conformance Profile

I think that the conformance profile is the right place to resolve backward compatibility issues.
It is increasingly becoming a practice to resolve this at implementation level.
For example, SOAP1.2 is not backward compatible with SOAP 1.1, but most stacks support both.
I have not heard of any complaint about it.
Also, many gateways support several protocols.
The conformance profile should take position on:
- V3 MEPs to use only V3 messages.
- the use of mapping rules  V2-V3 (in appendix)
- whether the PMode should be extended to V2 messages (using mapping rules above)
This can be finalized during 2nd PR.

Subject: [ebxml-msg] Addition to Gateway Conformance Profile

I would like the Gateway Conformance Profile for ebMS 3.0 to require that an ebMS 3.0 MSH also be able to support ebMS 2.0 functionality, at least at a basic interoperability level.


This requirement addresses end-user concerns that because of the updates in ebMS using some WS-* technology specifications (WSS, etc), that therefore ebMS 3 has incompatible differences from ebMS 2.0. It is important to assure those who have the ebMS 2.0 technology in production that there is no loss of ebMS 2.0 functionality when selecting an ebMS 3.0 MSH satisfying the main (full-featured) conformance profile.


I will be on a plane during the call today but hope to rejoin the TC meeting next week.
