I already made a proposal. From my previous note:

"If I had to make a suggestion, I would say WSD should provide some (optional) syntax to specify the old type of aggregation, and leave it at that. That syntax would simply collect a bunch of "new" services together under the same XML element. No need to base that syntax on any concept of common URIs identifying resources or other things."

This, by the way, corresponds to option #2 as expressed during the WSD F2F in [1]:

"2. service group definition
   <serviceGroup>
     <service>
     </service>
   </serviceGroup>"

I disagree. The wsdl:targetResource would be something different than our "service" concept, which I believe corresponds to the "new" WSDL service concept (collection of entry points with same interface).

wsdl:targetResource is something introduced to bring together a bunch of "new" WSDL services (a serviceGroup), so it cannot be identified with any of them (or it could be identified with one of them at the most).
