I also strongly suggest architecture group to start paying more attention to
the immediate needs of WS infrastructure starting with orchestration. As of
last conf.call, we seem to be winding a lot arround abstract vision

But, let me disagree with Waqar, I think that WSCL and all other similar
flow *description* languages whould fall under joint consideration of
architecture group (to fit it conceptually) and description group (to
finalize details of the spec). There are only three groups in W3 that have
to do with Web Services directly. According to the charter, anything
conceptual goes to WSAWG, anything descriptive goes to WSDWG and anything
"on the wire" goes to XMLP. Until a specific "orchestration" group is

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?
