I think it is to early to do this. For browsers that do not support MathML, the complete MathML code gets replaced by HTML or SVG as far as I can tell. Therefore it is no longer accessible by users of screen readers. That itself is in conflict with the idea of MathML and doesn't help at all. The semantics get lost completely. Not all people with the need of screen readers use Internet Explorer and the Math plugin. And there are still browsers like Chrome that don't support MathML. This becomes more problematic once we see laptops with ChromeOS and ChromeVOX. Therefore we should think about it twice. For the meantime I would like to see it removed from SVG 2 again untill we have a decision in the W3C with other WGs, including the MathML WG.

Greetings,
Dirk
