Hi Jonathan,
I doubt if I will be available for the meeting you mentioned.
Let me just say that profiled LaTeX, as in my talk at TUG 2010
<http://www.tug.org/tugboat/tb312/tb98hammond.pdf>,
provides a formal elucidation of the tree structure in any math expression
in its authorlevel XML document type. My project
GELLMU <http://www.albany.edu/~hammond/gellmu/> provides a didactic
example. In the didactic production system there's also another formal
elucidation of the math tree structure for each math expression in the
spawned HTMLwithMathML output, but the latter involves only the less
expressive vocabulary of presentation MathML whereas the former has a
vocabulary (for element names) that is close to the command vocabulary for
LaTeX. (Of course, the MathML there could be enriched using MathML
<semantics> to refer back to LaTeXlike names.)
I have not provided a good tuning of my didactic authorlevel XML for use
of the blind, but I think it should not be far away for someone who wants
to do that.
In my talk at TUG 2014 <https://tug.org/TUGboat/tb352/tb110hammond.pdf> I
spoke about the possibilities for direct "viewing" of (a tuning of) my
didactic authorlevel XML in a web browser using only CSS.
Thank you for providing this focus.
Best regards,
 Bill
