I think the jadetex back end uses tex text/math
distinction to decide whether to stick \ensuremath around the character.
The (La)TeX parts are as you say, a bit strange in places and have some
undocumented (and possibly unknown) dependencies on external packages
(I couldn't get the cyrillic to work last time I tried). There hasn't
been any work on the latex fields since the inital jadetex work of
Sebastian. All the recent effort has been on keeping the character
descriptions up to date as the unicode 3.1 and 3.2 proposals for
mathematical characters progressed through unicode/ISO and kept
shuffling the set of characters. I mentioned the file not because I
thought that the current TeX mappings are necessarily the best but
because it's a start, and if we update that file its easy to generate
unicode/xml -> tex mappings in various formats.

That's just another way of saying the latex field should have LICR
commands. For Latex use only it would be just as easy to define the
mappings directly in the latex package files but having them in that XML
would I think help translators from XML (especially MathML) to TeX to
come up with consistent mappings, as all the MathML entities and
character documentation is derived from there.
