I completely agree with you, automating python entities generation is on top
of my TODO stack see [1],

Along with this, there was always something more important to do, and
it was delayed time after time, so your help is most welcome.

sounds good, btw 5,6 can be constructed programmatically using __all__ generated by generateDS
and finding element name in xsd by type (from __all__).
