This is a step in the right direction, but I think it's still far from solving all interoperability problems in this domain. BPEL does not assume any particular WSDL bindings, so in principle anything goes. I could bind WSDL to SOAP over HTTP and have some good chances of interoperability. Or I could bind it to my home grown EDI system using my idiosyncratic XML Schema / EDI mapping, and have no chance on earth that anybody else could ever interoperate with me (while still being completely compliant with the BPEL spec).
