[vos-d] XOD questions

[Peter Amstutz]

My basic complaint with X3D was that the transition to XML could have 
been an opportunity to clean up a lot of the syntactical warts of VRML 
(delimiting index face sets with -1, for example) while still keeping 
the basic data model.  We could have had a schema that follows the best 
practices for XML document design, follows XML data types, etc and would 
have been a breeze for developers to support.  Instead, they choose to 
do a translation that amounted to little more than replacing curly 
brackets with pointy ones.

Having written a minimalist X3D loader (just geometry) it irked me that 
I had parsing issues -- Parsing Issues, in XML! -- between files 
produced by two different programs because of the extra syntax embedded 
in CDATA that wasn't part of the DOM structure.

I'm not saying it doesn't work, it is primarily an aesthetic issue -- 
but it does cause headaches for developers.
