First let's consider the picture without a circle saying "service."
Here the model we have:

    resource
        has one or more interfaces to mess with it
    interface
        has one or more bindings to use it via
    binding
        has one or more URL at which its available

What we call a <wsdl:service> now is effectively everything from
interface to the URLs. That is, the syntactic element really
captures everything from the URLs to the bindings to the interface.
The picture could be refined IMHO to have the circle be around
all of the things from resource up. Then the line connecting that
blob to resource is indeed what we capture with @targetResource
on <wsdl:service>.

No but you caught something as usual :).
