I disagree.  I think that for remotable interfaces, it is right and reasonable
to require that all interface types map to WSDL.  If this is not done, then you
have a difficult n x n mapping table to construct - and worse, I think it will
be hard to know whether any particular binding can be used for that remotable

The requirement for mapping to WSDL allows a much simpler approach both to
comparison of interfaces and also to the application of bindings.

For local interfaces, WSDL mapping should not be a requirement, but there,
the restrictions on mapping of interfaces will need to be spelled out.
