+%D Written at the end of 2007, this module is dedicated to Taco. Reaching this
+%D point in \LUATEX\ was a non trivial effort. By visualizing a bit what happens
+%D when pages come out of \LUATEX, you may get an idea what is involved. It took
+%D much time an dedication to reach this point in the development. Add to that
+%D those daily Skype intense discussion, testing and debugging moments. Time flies
+%D but progress is impressive. The motto of this module could be: what you see
+%D is what you get. An there is much more to come \unknown.

+%
+% todo: when mutable, remove immutable, decide on how immutable it really is
+%
+% todo: just for the fun of it we can compare the table generated here to mkiv but it
+% needs the same hash exposure as we use in luametatex so i'll do that after all lmtx
+% macros are checked (maybe i need to backport some more but it has a low priority)
+%
+% todo: do we need something similar for lua functions etc (problem: performance hit)

+% need to think about protection there (tricky as we use an avl hash there)

+ Some tokens cannot be created yet because they are more complex but eventually the creator will
+ deal with them. The indices are sometimes the same as internal but in most cases nicely start
+ at zero. When they start at another value, then there is an internal token or state that is not
+ user accessible. You always need to use symbolic constants as the numbers can change.
+
+ The first column is a classifier (which is experimental and categories might change when we feel
+ the need).

+%D \module
+%D [ file=x-mathml,
+%D version=2008.05.29, (evolved from pre 2000 code)
+%D title=\CONTEXT\ XML Modules,
+%D subtitle=\MATHML,
+%D author=Hans Hagen,
+%D date=\currentdate,
+%D copyright={PRAGMA ADE \& \CONTEXT\ Development Team}]
+%C
+%C This module is part of the \CONTEXT\ macro||package and is
+%C therefore copyrighted by \PRAGMA. See mreadme.pdf for
+%C details.
+
+% \xmlfilter{#1}{/*/name()} -> \xmltag
+
+% This implementation looks like a hack ... this is because we deal with all weird
+% cases we ran into, including abuse that was supposed to render ok (even if it
+% didn't in other renderers) .. it was simply expected to work that way. It is also
+% the product of stepwise adaptation to what we run into. And that in turn is often
+% determined by the tools that were used to produce the \XML. Even worse is the
+% cycling between coding that happens in projects: from content\ \MATHML\ to
+% OpenMath to asciimath to presentation \MATHML\ to \unknown\ which all depends on
+% what tools are available to render in a browser (where first \MATHML\ was hardly
+% supported, then became accepted, then was taken over by mathjax, then merged with
+% other input methods and who knopws what comes next in these days where technologies
+% are shortlived and the next best thing is already waiting around the corner.
+%
+% So, consider this module to be under constant construction and clean up. We still
+% use a funny mix of xml, tex and lua. I could rewrite the lot but it also shows
+% how context evolves. I might end up with a lua-only implementation some day, but
+% I must find a real good reason to spend time on it as so far it never paid back.
+% As far as I can tell, publishers have never shown much (real) interest anyway or
+% at least I haven't met one who cared to invest in it. If they run into \MATHML\
+% they just expect it to be supported.
+%
+% This variant is adapted to \LMTX\ and might evolve with upcoming variations of
+% the standard. As with \SVG\ and probably other \XML\ definitions that target a
+% specific domain, \MATHML\ is now more just something for browsers and \HTML\
+% usage (although support fluctuates). It's getting less generic (or at least we
+% see no more structural elements showing up) and with \CSS\ becoming the
+% recomended way to control local optimizations it indeed looks like only browsers
+% are the target, unless we can just ignore all that. Limitations of renderers,
+% specific usage, application determined \XML\ ... where will it end. All we can do
+% is follow and try to keep up, but maybe the more web it becomes, the less \TEX\
+% users need to care (read: can stick to \TEX\ coding).
+%
+% See the \MKII\ and \MKIV\ files for a history and the hacks we had to use in
+% the past.

+%D Since I only had the draft of MathML 2 and later 3 as example of rendering, there
+%D are probably a lot of omissions and misinterpretations. At least I learned some
+%D bits and pieces of math rendering.
+%D
+%D The main complications were not so much the math, but to find the most efficient
+%D way to handle elements without spacing beging messed up. The first implementation
+%D was aimed at getting reasonable output, this second implementation is already
+%D better in terms of handling nesting, and I will definitely need a third one that
+%D has more efficient and less ugly code.
+%D
+%D The \TEX\ part is not that complicated and once the preprocessor was okay, the
+%D rest way just a lot of keying and testing. It all comes down to gobbling,
+%D redefining, and not so much to parsing.
+%D
+%D The second implementation expanded the whole math sequence into an internal \TEX\
+%D representation. This is a rather clean and fast process. Filtering and testing
+%D takes place by redefining the internal representation macros.
+%D
+%D The third implementation may look a bit more messy in some respects. This is
+%D because in \TEX\ it's not that trivial to implement a tree handler. We use a
+%D stack for the \type {apply} element and other sequential content. Occasionally we
+%D need to peek into child elements which involves messy code. This implementation
+%D is closer to the normal \XML\ handling in \CONTEXT.
+%D
+%D This fourth variant just improves on the third. It uses some tricks available in
+%D \LUAMETATEX\ where we have extended the math machinery.
+
+%D We start with the parent elements and the option handler.

+%D We use inner and grouping (begin/end and no b/e) else we get problems with
+%D 1/2(1+2) and alike. The problem with apply is that we need to take care of
+%D several situations, like:
+%D
+%D \starttyping
+%D <apply> <.../> ...
+%D <apply> <fn> ...
+%D <apply> <apply> <ci> ...
