I actually think that WS-CDL goes beyond conformance aspects and addresses compatibility too. WSDL by itself only describes individual operations and their associated MEPs. (So if WSDL describes a one-way operation where WS-CDL expects a request-response, I can promptly say that the WSDL is no conformant). But WSDL does not say anything about the sequencing of operations defined in the interface, and the sequencing comes from the implementation (e.g. the BPEL behind the WSDL). So WS-CDL is also concerned with compatibility. Ugo
