After having the opportunity to speak with Ira regarding this, we think 
there may also be an "option D" which is to describe normative Soap v1.2 
but supply NO WSDL example at this time.. rather indicate that WSDL 2.0 is 
in progress and it is our intent to supply normative WSDL following 
adoption of WSDL 2.0 as a W3C candidate recommendation.

WIMS> Normative Ref to WSDL/2.0 would block WIMS as PWG CS


Per the WG last comment on WIMS Protocol spec last week (for examples
of WSDL definitions and actual SOAP messages), I've been working on WSDL
for the WIMS Protocol -  following the excellent examples in the recent 
WS-Polling submission from IBM to W3C.

Good News - conveniently, I recently released the WIMS Message schema,
which is most of the work - the WSDL itself is very small by comparison.

Bad news - we all repeatedly agreed to make the non-standards-track
bindings (using WSDL/1.1 and SOAP/1.1) _optional_ for compatibility and
make standards-track bindings (using WSDL/2.0 and SOAP/1.2) _mandatory_ 
to implement.

But, the W3C site now says (at http://www.w3.org/2002/ws/desc/):

"Below are the targeted publication dates for the WSDL 2.0 drafts:

  Second Last Call
    June 2005
  Candidate Recommendation
    October 2005
  Proposed Recommendation
    Early 2006"

PSI/1.0 fudged on this and standardized a SOAP/1.1 binding described in
WSDL/1.1 (calling them 'defacto industry standards' - which is true, but 
they're still not interoperable).

So the WIMS/1.0 Protocol spec will have to:

(a) Use the above SOAP/1.1 fudge for normative bindings;
(b) Wait for the approval of WSDL/2.0 (now a working draft) by W3C;
(c) Use SOAP/1.2 for normative bindings
    and INFORMATIVE references to the WSDL/1.1 W3C Note 
    and INFORMATIVE examples of WSDL/1.1 for the SOAP/1.1 binding.

My apologies for not realizing this problem earlier.
