Well, as Mike mentioned before, SOAP and WSDL do not have notion of state. So if we want to talk about state we have to move to a level above that. (You might want to call that a semantic view of what the service actually does). I used the BPEL Web service example because in that case you have a specific document (the process document written in the BPEL language) that tells you what the internals of the Web service (i.e. the business process) look like.
