My project 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 HTML-with-MathML 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 to refer back to LaTeX-like names.) I have not provided a good tuning of my didactic author-level 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 I spoke about the possibilities for direct "viewing" of (a tuning of) my didactic author-level XML in a web browser using only CSS. Thank you for providing this focus.
