FYI, I attached the error in a text file as it was poorly formatted.

Any ideas on why the attached WSDL may be causing a
NullPointerException as a proxy on startup?

From the trace it leads me to believe it's related to the binding.
Are there any requirements on things being in different namespaces?

FYI, these WSDL's and Schemas work fine with JAX-WS RI as well as CXF.
It just seems Synapse/Axis is breaking.

I submitted a bug, but I'm guessing that probably wasn't necessary.
