[x3d-public] X3D 4.0 update to XML encoding has commenced, comments welcome

[John Carlson]

Don,

I would like to see name attribute types handled consistently.  I believe
there are at least 6 cases where type=‘xs:NMTOKEN’ and
baseType=‘xs:NMTOKEN’ and xs:NMTOKEN gets puts into x3d.py in type
expressions, and that breaks x3d.py (colon is not recognized).

Primarily this has been an issue with my version of the x3d.py, but I have
been fixing upstream code to change to type=‘SFString’.

I believe the change was made when you incorporated Holger’s changes.

Please verify that all xs:NMTOKEN references in x3d.py are correct.   My
suggestion is attempt to modify upstream files like the X3DPSAIL
stylesheet, X3DUOM and XML schema.

I have provided updates to X3DUOM which allow my version of X3DPSAIL to
work.  Other patches are more difficult .

Getting this right is vital to the success of a Blender exporter using
X3DPSAIL.

Call me or set a meeting to discuss the changes as I am out of my element.
It’s highly likely you may have patched them already since 1-2 weeks ago.
It’s difficult running with tons of unapplied patches.

I will look into repairing X3DPSAIL if you view this a non-issue for the
XML spec.
