[x3d-public] X3D JSON Schema Updates: determining event constraints forSFTimedurations and timestamps

[Don Brutzman]

XvlShell is present as an example of adding extensibility to an XML DOCTYPE (DTD).  The Xvl nodes are merely experimental: not approved by the X3D Abstract Specification, not in the X3D XML Schema, and not in the X3D Unified Object Model (X3DUOM).

http://www.web3d.org/x3d/content/examples/Basic/LatticeXvl/

I believe that you will find that each of the models in that directory contains the error statement

	<meta name=' error ' content=' Test X3D DTD experimental extensions mechanisms, the XVL nodes are not legal X3D '/>
