Dear Jeanne: APA had a productive conversation regarding your question on our regular weekly call today. The conversation is logged here: https://www.w3.org/2020/02/26-apa-minutes.html#item02 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.
