Understood, but that was my very point : you may know what features AAT fonts have, or Graphite fonts, or whatever (I don't : I don't even know what they are !), but the end user of a font selection mechanism should not need to know. He/she should (IMHO) be able to express him/herself in abstract terms and have the font selection mechanism map these onto font-type-specific features as appropriate.
IMO it is not possible to have a "universal syntax" (there are also graphite fonts) without losing format specific functionality.
I am not convinced, but I respect your right to hold this opinion :-) ** Phil. -------------------------------------------------- Subscriptions, Archive, and List information, etc.: http://tug.org/mailman/listinfo/xetex
