Hm. I thought that MathJax maps the presentation markup and not the content markup… I am looking at the examples in, e.g.:

http://docs.mathjax.org/en/latest/start.html <http://docs.mathjax.org/en/latest/start.html>

Just to clarify your comment: you say that in the final EPUB file an SVG should/would be good enough for Math, right? I would agree with you except that if you want to add interaction to equations then (though feasible) it becomes probably a pretty complex SVG. Ie, if MathML could be displayed really quickly (ie, interactive speed) then attaching callbacks, colour changes, etc, would be way easier if it was scripted directly on the MathML level.
