Don, we are concerned about the python links on these pages producing
incorrect XML output.  Can you provide updates to x3d.py, if there are
updates?   Otherwise, I'm afraid Andreas' and Vince's points still stand.
We really need updates to x3d.py.  We would like to try to patch it with
your permission. We would like to add containerFields as best as we can to
the output of x3d.py. It's not that we can't patch output from x3d.py.  I
hope you understand that we don't want to hand edit x3d.py output as that
would look bad for the Web3D Consortium to produce files from x3d.py that
required hand editing. Especially if someone is downloading x3d.py from a
website and does not have these threads handy to to read.

If you like, I can download the XML, convert to python, then produce XML
from the python code (using x3d.py off the shelf).  But I'm afraid I will
get the same results as Vince and Andreas.

Andreas did address some of the solution.  See his link to the stylesheet
in question, which I provide here:
https://sourceforge.net/p/x3d/code/HEAD/tree/www.web3d.org/x3d/stylesheets/X3duomToX3dPythonPackage.xslt

Thanks,

John
