Steve,

Let me try to clarify the intent (it seems to me that there is a deep 
misunderstanding).

The charter does not limit itslef to solutions like WSDL-S. The idea is
to think about building a technology stack, starting from WSDL, adding
some semantic extensions (generic enough to be able to build on top
of these) and continue on those footprints. The goal is precisely to
define the scope of what could be done (invocation? discovery? more?).
The proposal is to find out and demonstrate what can't be achieved
with the current Web Services technologies.

Again, the charter does not exclude any of those, because those 
particular "key points" should be determined by the group.

Restricting the scope to the fields that are already addressed by 
existing technologies is IMHO a bad idea for characterization. The goal
is to derive the functionalities from the use cases, not from the
technologies developed in the area.

I hope this helps.
