These are my initial impressions on the kind of requirements WSCL places on WSDL. 1) WSCL is a very minimal set and does not clearly provide many details needed (such as a clear mechanism for making abstract concepts concrete). So it is hard to determine what kind of requirements might be placed on WSDL. 2) It does seem like at minimum, WSDL will need to be able to model interactions as operations. Since WSCL operations all use document centric computing, The message parts in WSDL should be able to handle attachments. This is already covered by use case UC0006. 3) WSCL errors have to be mapped to faults. The mechanism should be similar to the one above. 4) WSCL defines 4 types of interactions. Those 4 types of interactions match the 4 kinds of operations described by WSDL. 5) WSCL conversations are clearly out-of-scope for WSDL. 6) I am fuzzy on how WSCL expects the protocol bindings to be specified. In general, WSCL seems to be incomplete. Just like WSDL, It defines the abstract concepts. Unlike WSDL, it does not define how to make those abstract concepts concrete. That seems to represent a grey area. For right now, I could not see any other requirements jump out of WSCL. WSCL is not as rigorous as WSFL in mapping to web services. My confusion is that it seems like the lack of rigor in that area is by design and I am not sure why? Anyway, I don't not mean for this thread to become a discussion of WSCL so I will leave it there.
