+-- Afterthought:
+-- Different citation commands are essentially typographical instructions:
+-- they are concerned with the final representation of the data with respect to
+-- a concrete implementation. Not the thing at all that would make reST
+-- portable. But then its support for Python-style string escaping &c. ain’t at
+-- all portable either. 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. Keep in mind
+-- that zapf.tex is not just random dummy text. Now, where was I?
