The problem is the same with XML written to be --- processed with ConTeXt -- when processing the text directly in MkIV you’ll --- always find yourself adding setups that allow fine-grained control of the --- typeset output. At the same time those instructions directly contradict the --- main reason for XML: to provide an application-independent data markup. --- Typesetting XML (and now reST) with TeX, you will always end up writing TeX --- code disguised in XML brackets. (Btw. the docutils reST specification has --- the same kind of inclination to HTML -- some of its components don’t even --- have a meaning save in HTML peculiarities.) If you strive to avoid this --- *and* would like to have decent typesetting, you should use the --- automatically generated TeX code as a starting point for the actual --- typesetting job. Wish it was possible to have both -- the data in a --- universal form and the output in the Optimal Typesetting System -- but --- that’s a dream for now. If you really read these musings, then prove me --- wrong if you can! Or go tell those digital publishers and their willing --- subordinates, the authors, who think they can save a few pennys, --- substituting the typesetter and editor by some fancy software.
