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.
