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).

WSDL 1.1 to WSDL 2.0 mapping

one of the more difficult questions i'm being asked at the moment
is how we will migrate from our WSDL 1.1 documents into WSDL 2.0
when it arrives.

This task would be vastly simplified if there was a standard mapping 
between the two languages, with an indication of which WSDL 1.1 features
cannot be expressed in WSDL 1.1 and vice-versa.

Given we now have a nice component model for WSDL 2.0, is it feasible
to provided WSDL 1.1 serialisation and deserialisation for WSDL 2.0 ?
If so, could this be written up as a W3C note under this WG ?
