Re: WSDL 1.1 to WSDL 2.0 mapping

There is already a non-normative, but rather empty, appendix
on this topic. I intend to work on it sometime in the future .. I agree
that indicating how to go from WSDL 1.1 to 2.0 is crucial.

Furthermore, I'd like to write a separate document (to be published
as a note if the WG wishes to or I can publish it on IBM developerWorks
say) which defines a WSDL 2.0 compatible profile of WSDL 1.1. I'm
certain that can be written as a subset of the BP 1.0 profile of WSDL 1.1.
If that can be achieved then we should be encouraging people to stay
within that profile so that moving up to WSDL 2.0 becomes mechanical.
(I intend to write an XSLT transformation for that profile; interested
parties
can easily extend that profile for greater WSDL 1.1 coverage.)

Sanjiva.

> There are things in WSDL 2.0 that cannot be expressed in WSDL 1.1, e.g.
interface inheritance. However, it is probably feasible to imbed WSDL 1.1
into WSDL 2.0, although you may have to invent some extensions (e.g. for
SOAP encoding).
