Although it appears on the surface that people are disagreeing here, it
seems to me that most of the participants in this discussion are more or
less on the same wavelength and are primarily expressing themselves a
bit differently or possibly disagreeing on subtleties or nomenclature.
So ... Would it be reasonable to try to harvest something out of this
discussion?

I am NOT volunteering -- I do not feel that I am competent to do this
task.  I am merely observing that it seems like it might be done by
someone with a better overview of things than I possess.

Semantics is always a vague concept, so let me try to further clarify.
What I was referring to is something that describes the internal
behavior of the service and is currently not expressed in the WSDL
interface. To take Chris' example, if a client sends a message
containing two coordinates to a map service with the expectation that
the service will refer to a map that the client previously retrieved,
this particular server behavior is what I would say to be part of its
semantics (i.e. not expressed in the interface).
