RE: [APG] Further Follow Up Math and MathJAX

Thanks Rich.

How do you see the MATH role in ARIA supporting identifying math in a web page.

I agree using somethings like ARIA to annotate somethings like SVG is not the right solution due to structural issues. We need to get access to the MathML

So, at this point JAWS only supports MathJAX in IE. Chrome nothing is supported. Firefox supports native rendering of MathML which ATs can access.
On Macs: Safari renders MathML directly.

ChromeVox supports MathML via MathJAX, since it accesses the DOM directly and can make JavaScript calls. However, the next generation of ChromeVox operates on the same tree that is used to support accessibility APIs, and I don’t know what the implications are for its MathML processing.

VoiceOver under iOS with Safari includes extensive MathML support.

It should also be kept in mind that MathJAX is not the only MathML rendering library in use; KaTeX is another option which is often mentioned in this connection.

I have heard the hope expressed that ARIA will step in by adding roles to support the various mathematical structures, allowing the HTML and SVG produced by libraries such as MathJAX to be annotated. I’m not convinced that this is the right solution, and I have questions about whether it would be workable, especially if the order in which the rendered HTML and SVG elements appear in the DOM tree departs from the logical reading order of the mathematical expressions.
