[x3d-public] Diamond Main 0, first looks:

Sat Nov 4 16:18:01 PDT 2023

Don, please follow this thread carefully.  There are many things flying
around, but primarily, we want X3dToPython.xslt produced python programs
using x3d.py to be able to output XML that is immediately validatable and
viewable.

That’s a good goal, right?

Thanks,

John
