Hi Zheng,

I'm the co-chair of the MathOnWeb CG. Some inline comments.

That's a misunderstanding. The link points to a specific task force within
the CG which is currently inactive (for lack of developer interest).

The MathOnWeb CG is currently focusing on identifying improvements to CSS
that help existing equation rendering solutions (including those digesting
MathML). We also work on accessibility issues relates to mathematical

As oppposed to anything related to MathML, both of these topics are
actually active areas of development and research across various projects
and organization, many of which are open source.

It is true that the CG is not concerned with MathML; then again, no CG has
the relevant standing. Historically, the CG started while the MathWG was
still active thus MathML was obviously out of scope.

If you study the CG's minutes you might find that most of the active CG
members do not consider MathML a viable solution for the web, neither for
visual rendering nor for accessibility purposes. SVG, CSS and ARIA are
better suited for these purposes.

Since I used to manage the MathJax project (and helped with Readium's
implementation of MathJax), I'd encourage you and any other rendering
system to get in touch with the MathJax team; I'm happy to make
introductions. There are many ways around current performance issues and
MathJax v3 (currently in alpha) will also greatly improve performance and

Best regards,
