You can find my rants about the practices in SOAP land on various
places. Come to my talk at the German Perl Workshop this Wednesday
and I will present a long list of schema and soap horrors.

When someone develops the idea that applications should dynamically load
the WSDL from endpoint?WSDL at start-up, then you must be extremely
unexperienced with maintenance.  But disappointingly, many developers
follow this dark route.

Be glad you get an error, so you can repair your application.

I have been thinking of an option interpret_required_as_optional.
However, there are so many places where this will break the inter-
pretation or more complex structures.
