There is a BNF grammar for the built-in Inventor nodes and fields at

It doesn't include WWWInline/WWWAnchor, includes a lot MORE than VRML, and
doesn't include user-defined nodes.

YACC can't handle all of Inventor because the extensibility features make the
grammar dynamically extensible (are there any parser-generators out there
that allow self-describing data?).
