[X3D-Public] announce: X3D Schematron rules for node misspellings, updated X3D Validator, X3D-Edit

[Don Brutzman]

New feature in X3D Schematron rules:  detection of common 
miscapitalization and spelling errors in node names.

Example warnings:
- Nodes such as Arc2D should be spelled 2D (rather than 2d)
- Similarly for nodes mistakenly containing 3d or 4d
- Node name prefix capitalization must start with CAD, DIS, Geo, HAnim, 
NURBS
- Mixed case errors like Arcclose, MetaData, PolyLine, PolyPoint, Lod, 
Connect, Export, Import, Is, Navigationinfo, ViewPoint

These are helpful because other XML validation reports can be confusing 
for these simple error cases.

Also updated:
- X3D Validator is at https://savage.nps.edu/X3dValidator
- X3D-Edit online  at https://savage.nps.edu/X3D-Edit

Comments welcome.  Have fun with X3D!
