John, what if it is the processing model that defines the 
data representation, in effect, the means of declarartion?  
VRML is an application language that from the inception was 
targeted to object-oriented implementation.  Is the XML 
system of a root based, positional hierarchy with attributes the right 
way to express a node based definition in which hierarchies 
are expressed as field types?  While the groves definition 
is clean, the XML definition forces us to choose 
between wrapper tags or the XML property set for the hierarchy.
The crux is wrapper tags to name fields such that the hierarchy is
rootless even if the grove definition has a synthetic root.
