In general we agreed with what you say below on the last PF call. However, some felt that specifying TeX or whatever should be a best practice and not in the spec. See the thread I started called 'New role="math" in ARIA, how to author and how browser would expose it' In that thread we're discussing some of the remaining issues, and you can see the current definition. - Aaron "Simon Pieters" <simonp@opera.com> Sent by: w3c-wai-pf-request@w3.org 03/05/2008 12:18 PM To unagi69@concentric.net, "Gregory J.

I would suggest that it be defined exactly what role='math' means so that implementors and authors know what to do, as in e.g.: Definition: content that represents a mathematical expression expressed in TeX. [TEX] If the element is an HTML "img" element, then the content of the alt attribute represents the expression, otherwise the element's textContent DOM attribute represents the expression. [HTML4] [DOM3CORE] (I don't know if TeX is the best way to represent a mathematical expression in plain text, but in any case I think we need to say which it is and not let it be an open-ended anything-goes.) -- Simon Pieters Opera SoftwareReceived on Wednesday, 5 March 2008 18:17:53 UTC
