Subject: RE: [wsbpel] Are WSDL descriptions always required for abstract processesHI Tony,BPEL spec section 3 clearly states its dependency on WSDL1.1. As one example of the dependency, partnerlinktypes are defined as WSDL extensions. how a process can be constructed without a partnerlink?Best Regards,
Kevin

Subject: [wsbpel] Are WSDL descriptions always required for abstract processesDear Colleagues,I would like to see if there is a simple and agreed answer to this question or whether I should raise as an issue (or add in to an existing issue such as 82 or 97).My question is:Are WSDL descriptions *always* required for abstract processes. Is the answer clear and correct in the specification?Imagine an process (A) that communicates with three remote processes (B), (C), (D). Is it possible to produce an abstract process BPEL description on its own (one XML document) that conforms to the schema and to the letter and spirit of the textual specification, or is it required to always produce WSDL descriptions as well - if so how many and for what? Three one for each of the 'A' ends of the A-B, A-C and A-D relationships, three one for each of the 'B', 'C' and 'D' ends of the A-B, A-C and A-D relationships respectively, or all of these making six in total?The spirit of section 15.1 (and especially the second paragraph) might be taken to suggest that the WSDL descriptions are not required.However, as Ugo has pointed out to me, the portType attribute is a qualified name type and is a required attribute on invoke, receive and reply, which implies that mechanistically the WDSL descriptions are required at present.What say you Senators?Best Regards,
Tony
