Let's not fail to notice that, for example, SP/OpenSP and therefore
Jade/OpenJade (the last time I looked) also do not support plane 1.
With SP there is a kludge to "adjust" the DTD for our current plane 1
needs, but that will no doubt break for general needs.

For a maximally LaTeX-like authoring(*) interface in gellmu, a few
features of SGML not part of XML are needed, and eventually I would
like to have high plane support.  But I'm not the right person to add
this functionality to SP.

As we think with Ivor Phillips and Stan Devitt (see

   http://www.mathmlconference.org/2002/presentations/phillips/ )

about the very significant community of TeX/LaTeX authors, and the
call that we test converters such as tth/ttm and tex4ht/mml, we may
come to find that some conversion needs for legacy documents might be
met with SP by using what I might call "markup hijacking" in gellmu.
(See http://www.albany.edu/~hammond/gellmu/teaser/ in the case of
hijacking gellmu source for html into gellmu source for gellmu/article.
The item "lfaq" in the gellmu examples archive is an example where
LaTeX markup for the UKTUG faq of some time past was ported to
gellmu/article with a great deal of help by markup hijacking.  In this
case the resulting gellmu source is somewhat inefficient.)

"Markup hijacking" should not be confused with "markup appropriation",
which is where one, for example, creates a slide set by using sections
for slides in an SGML model of LaTeX article and then formats it with
the LaTeX slide package du jour.  (For an example of this see

   http://math.albany.edu:8000/math/pers/hammond/Presen/tug2001/ . )

(*) P.S. to LL: I think we should accept the fact that the noun
"author" has been verbed.  :-)
