Dear Jeanne:

APA had a productive conversation regarding your question on our regular
weekly call today. The conversation is logged here:


SUMMARY of Our Recommendation

*	Use current MathML, because it's a W3C specification. W3C specs should
*	leverage other W3C technologies.

*	Charles LaPierre (of Benetech) and Dr. Jason White (of ETS) are
*	both directly involved in W3C work to better support
*	accessibility in mathematics and chemistry markup via W3C
*	specifications. They offered to review the draft specification
*	text for correct MathML usage based on most current best
*	practices.

*	At this time a polyfill script must be sourced by the
*	specification document in order to properly render MathML in the
*	browser (and provide accessibility support for examining the
*	MathML) content. MathJax<https://www.mathjax.org/> is
*	recommended for this functionality, and specifically the
*	recently released MathJax version 3.0.1 (which fixed several
*	accessibility issues of MathJax version 3.0). It is reasonable
*	to expect that no polyfill will be required by the time WCAG 3.0
*	transitions to CR/PR/TR, because MathML support is actively
*	being added to browsers.

*	W3C pubrules do not ordinarily allow sourcing such scripts in TR
*	publications, so the AGWG Staff Representative will need to
*	obtain an exception from W3C systems management. In order to
*	begin that process, candidate content would help.
