Going even further off-topic, but pursuing this one aspect of the thread, is there not only real one problem : the need to educate users to cease marking up their documents in raw (La)TeX syntax, and instead to express them in well-formed XML ? I have just finished typesetting (using [plain] XeTeX) a 544pp book marked up entirely in XML, and whilst I have made no efforts to generate PDF/UA, I am convinced that the task of so doing (assuming that the necessary primitives are or were available in XeTeX) would have been 1/1000 of the effort needed to do so had the book been marked up in traditional (La)TeX syntax with its usual accompanying conflation of form and content. ** Phil. -------------------------------------------------- Subscriptions, Archive, and List information, etc.: http://tug.org/mailman/listinfo/xetex
