David, I didn't miss the point at all. My point is that if you want "simple", you have SOAP/WSDL. If you want reliability, security, etc., that's what we have done that SOAP doesn't have. However this rich function comes at a price of some cost for generating compatible configurations. One way of extending MSG/CPPA for B2C is by allowing a service provider to publish a CPP (or a CPA template) that is a take-it-or-leave-it CPP. "If you want to do business with me, you set up this way." That might be fine for customers but it probably wouldn't be sufficient for B2B. However, many people will ask, why not just use WSDL?

C. Jones (E-mail)" <[email protected]> Subject: RE: [ebxml-msg] Messaging Spec v1.092 Marty I think you miss the point. SOAP is not fit for purpose as it does not include reliability and security. What we really need to do is extend SOAP/WSDL to include security, reliability, end-to-end acks, etc, but in the declarative, take-it-or-leave-it style of WSDL **as well as** the negotiated way consisting of the merging of templates that I think you are suggesting. Remember, I really am not anti-CPA, I just want them to be used in the right way i.e. to record the agreement between two parties where they want to constrain how they do business together. David
