Great example. Now assume that Ma & Pa want to advertize a URI for subscribing to their service _without_ implying the binding that will be used in the URI. How do they do that? You obviously can't send out any of the soap:address locations, since they imply a transport. You can't send the URI of the "ma-pa-market-service" element, since that is for more than one interface. Seems you would need to send out two URIs -- the one for "ma-pa-market-service" and the one for the "ma-pa-market-admin" interface. Two URIs are necessary in order to refer to the most useful concept that is provided by WSDL: a reference to a service independent of the mechanism used to communicate with it.
