The H-Anim group has discussed putting it out as a separate document, Matt Beitler is reportedly doing that already. Each node will flagged as what profile they are in. We then had a length discussion on organization terminology. This meanders here in the notes a bit but then focuses nicely. Example profiles are Core, Base, and maybe more.
Profiles have conformance criteria.
More definition work is needed. Tetrahedron node definition would be derived from a Geometry node type, since it can go anywhere in scene graph that a Box, Sphere or other geometry can go. We have promised a small number of profiles, so that they match targeted author expectations and also targeted audiences. GeoVRML as a profile would have to name all of the nodes needed, e.g. it would need to include the Shape node. Sandy will ask Mark.
