This is an archived snapshot of W3C's public bugzilla bug tracker, decommissioned in April 2019. Please see the home page for more details.
[Filing on behalf of John Gardner] User agents should treat a <math> element's "alttext" attribute as equivalent to an "aria-label". When present, this text should be added to the AT agent's speakable buffer in place of a plain-text rendering of the math symbols. HTML Task Force in discussion is unclear in this case whether it's a question for the HTML spec or the MathML spec, since this is "inside" the math element. Filing this bug to meet deadline but will need to figure this out.
