LANG: normal binding

Sorry to interrupt the discussion for a technical language question
(is this the right list to do so?):

In case NormalBinding is set to PER_FACE_INDEXED (or
PER_PART_INDEXED), does the normalIndex array of IndexedFaceSet have
to contain a "-1" after each normal index or not?

BTW: most VRML files I saw, either provide a normal vector per vertex
to allow smooth shading or do not provide normals at all and rely on
the browser to create one normal per face for flat shading, which are
the most useful alternatives also from my point view.

bye,

Michael Pichler
