Since I haven't managed a workaround
for the 'Typemap' branch to generate classes
other then interface, I decided to experiment
with the XML::Compile::SOAP / XML::Compile::WSDL11 modules.
and success! (Although there seems to be a bug in those modules
related to hexBinary type, it was workable)

XML::Compile however doesn't provide a wsdl2perl type of code generator,
which is my preferred way to create my needed set of APIs.

I'm looking forward to trying out updates to SOAP::WSDL when these
issues with deep recursion, and class generation are solved.
