We might be converging on something here ... A web service is defined by the
FUNCTIONALITY of SOAP, WSDL, and perhaps UDDI; those are in some sense
"ideal type" definitions of a web service, but so long as the interface is
rigorously defined using some combination of URIs and XML, we agree that it
is a "web service."  Are we getting there?

Actually, discovery ("UDDI functionality") probably doesn't have to be as
rigorously defined as the envelope format and message exchange pattern
(SOAP's functionality) and the actual format of the invocation/response
(WSDL's functionality).  An "invitation only" service is still a "web
service" ... Does anyone disagree?
