I am cross-posting this to the architecture group also.  I personally
believe that a description language and orchestration language belong to
different stacks in the web services reference model (none exists yet).  

I believe that orchestration layer adds a level of business intelligence
that leverages the web services layer (described by WSDL) but the two are
not the same.

I vote to defer WSCL to the architecture group for consideration and not
change the scope of what we are doing with WSDL.

[Switching to w3c-ws-desc, since this may touch on member confidential

Orchestration brings the question: what are we supposed to do with WSCL [1]?
This does not seem to be considered out-of-scope [2], and the team's comment
was that it should be brought to our attention [3]. Does this indicate a
possible refinent for operations?
