Agreed.  I need to understand what it means though to an 
implementation of a RELAX NG spec'd language.  In X3D 
as in other languages, we have the primitive types of the 
language, eg SFString, MFString, and so forth, then we have 
the built in node and field types, eg, Sphere, Indexed Face 
Set, and so forth.   The PROTO node is used to create interfaces 
for adding behaviors and fields to existing node types but there 
are issues there about these being first class objects.
  
What I am asking myself is where the bolt-in type capability 
of RELAX would fit in, and my guess is, in the primitive types, 
so for X3D, for things such as MFString.

XML et al end up having a buffet table of typing features, and I 
am realizing the degree to which I really don't understand 
their interrelationships and how to choose wisely the features 
given an object model.  Call me turkey dense, but I may not 
be the only flapping hard and going nowhere.

Nor should we confuse the predator of the animal with the animal.

Bolt-in types good, though.
