There is a granularity of identity issue there. One does not typically extract one face from an indexed face set and use it elsewhere. Maybe the same can be said for a line segment or a single coordinate. One can argue as some will that meaningfulness is with the user and that the format should enhance that to the maximum degree possible. On the other hand, coordinates, for example, are seldom atomic as meaningful units except to the renderer unless one is working in a geo system of map coordinates where coordinates are paired with meaningful names (think intersection of two highways). So in isolation, the decision to use a number list makes sense. When one considers reuse in a different semantic system, the case can be different. How theoretical is this? I don't know and maybe it varies case by case, but it still seems odd to me to have at least four XML languages with four different dialects for coordinates. We may wish to look at different combinations of namespaces to see just how jangly the clash really is. X3D and SVG are, IMO, obvious examples of an opportunity to work together. CAD formats (computer aided design) are another but are a bit further into the future. len From: Simon St.Laurent [mailto:simonstl@s...] If it's a wrapper format, fine. Call it a wrapper format. Don't sell it as a new XML format. This spec appears to be creating a whole new set of semi-random numbers and letters, and calling it XML. >Lists of numbers are common, BTW. X3D has them too. >But when SVG and X3D finally do merge in a meaningful >fashion, it will be painful to work in namespaces where >each one has a different way to specify coordinates. Even for people merely converting from one to another, never mind grand unification, this creates huge problems. SVG does get criticized on a semi-regular basis for this. Dunno about X3D, but it'd be a huge black mark for me. Maybe they don't care - "it's just a delivery format" - but I spend too much time extracting information from delivery formats to take that claim seriously.
