[x3d-public] Discussion: containerField for x3d.py XML export

[John Carlson]

Again, I'm targeting 0 warnings, although missing meta node content
attributes *might* be acceptable.  Stuff like copyright.  We can ask
Michalis not to report containerField warnings, meanwhile, I don't want to
keep adding containerFields, so patching x3d.py becomes attractive...should
I build a whole Pascal environment to build my own view3dscene???? I
haven't used Pascal for 40 years!

I don't think normaloids want to get in and patch their copyright contents
field, so a required entry in Blender would be great. Doug?
