While most do, it's not necessary. The grounding can be extended and,  
in fact, has been to directly map to UPnP services.

Of course, it's probably not *wise* to do that. With WSDL 2.0, it  
would be smarter to extend the WSDL with a new binding. In a sense,  
this distance from WSDL is an historical artifact.

Yep. You just need that your atomic services are somehow grounded in  
something "directly" exectuable.
