Hi Peter,
Once again, huge thanks for the response! Your comments made it "click" as
to how the bindings work. As you guessed, I do (or should try at least)
need to generate all bindings at once. All of the "other.xsd" files imports
netconf plus one other xsd. I noticed the "_nf.py" module being created as
I generated modules from the other tertiary sources so to speak. After
working with the examples from the source, Python is starting to make more
sense which in turn helps me understand PyXB the more I am using it.
(Coming from Perl and PHP :) Python seems so literal and quite eloquent ...
I'm really starting to like it. The PyXB module rocks!!
Thanks again for the nudge in the right direction :)
Max
