We want to model VR scenes as a collection of objects. VRML is used to
specfiy the objects' data while associated scripting languages are used
to specify the methods for the object classes. This allows you to cache
object data and methods *separately*. The issue at stake here, is the
formal model behind VRML that will allow you to specify data for novel
object classes without forcing those classes to be built into the core
language spec for VRML. My proposal will also allow you to syntactically
verify an arbitrary VRML "document" by checking against formal data
models for such novel object classes via network declarations at the
start of each VRML document.

Best wishes,
