[X3D-Ecosystem] XML is dead for x3.py

[John Carlson]

I have used the ant target

ant create.X3DPSAIL to create x3d.py, then applied the awk script I just
sent.

I'm running a full regression test with  the new x3d.py soon.  I'm
currently doing Java compilation.  Python is last.

I've run some tests with my PythonSerializer in  the mean time,and caught
some bugs in it, but I should have plenty of Python waiting for me to test
now.

I'm off.
