+%D A \type \type {\let} is more efficient than a \type {\def} so we often let something
+%D to relax or do nothing. However, we then loose the name in tracing. For that we now
+%D have \type {\lettonothing \foo} which is efficient but also keeps the name. Of course
+%D this is no solution for commands that take arguments but at least it helps tracing a
+%D bit. We keep of course \type {\donothing}.
+
+%D Maybe even nicer is a let that aliases but keeps the name.

+%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.
