(* VR10 is based on VR9e with changes to tessellated_face and tesselated_surface_set (adding new subtypes) 
and deletion of triangle_set and complex_triangle_set *)
(* VR10 corresponds to EXPRESS in Part 42 DIS document *) 
(* VR9a is based on the EXPRESS of V7R8a with changes proposed and agrred by email discussion  
In VR9a the triangle_set definitions associate normals with points *)
(* 2 new select types introduced to reduce number of optional attributes *) 
(* VR9d replaces BOOLEAN with LOGICAL type for smooth attribute of connecting edge *)
(* V9e incorporates changes to tessellated_face, tessellated_surface_set and tessellated_connecting_edge
WRs from ISO meeting review *)
