But I didn't suggest it because all I can take care of are the minor modifs I mentioned. Delving into the arcane depths of format conversion would just use up all of my little TeXmacs-time.

Good to hear that it seems easy ;) There is also some specificities of html5, outside math support (like > article, or figure tags) which are interesting from the semantic point > of view.

Needed for some browsers as stated in the document you linked. http://docs.mathjax.org/en/v1.1-latest/mathml.html#mathml-in-html-pages 4) Add the mathjax script to the header. This could be customizable (i.e. options: "Use MathJax CDN" and "Use custom MathJax installation") I guess my suggestion of a single configuration option "texmacs->html:math" is then ok. It would have the values "html", "mathml", "image", "mathml+mathjax". HTML/XHTML export should be independent (at least to the user, since we have to fix MathML+HTML (step (3)). I can take care of (1), (2) and (4) (hehe, sorry), leaving (3) as-is: output will work in decent browsers. Then someone can try tuning mathml output when destination format is not xhtml.
