Sanjiva, I like your proposal. In particular, I think there is a
lot of merit in bringing the notion of an abstract service into
the foreground. Please find my comments below.

This is fine...

... however I don't think we can require the wsdl:implement
element to be always present. For example, the WSDL file may only
contain an abstract service declaration, which is refined and
implemented in a second WSDL file. I think wsld:implement should
be optional unless there is a concrete service definition (i.e.
binding), in which case it should be mandatory.

Hmmm... somebody could get it wrong and you could end up with two
portType with the same qname but different children EIIs. It's
probably not our business, though, and more like a programmer's
