http://www.w3.org/Bugs/Public/show_bug.cgi?id=12587 --- Comment #2 from Leif Halvard Silli <xn--mlform-iua@xn--mlform-iua.no> 2011-05-03 13:01:31 UTC --- Here is the approach which the 'HTML to Platform Accessibility APIs implementation guide' should take: 1. The AT should first run an algoritm to *calculate* whether the IMG is presentational or non-presentational 2. If it is non-presentational, AT should select the best text substitute When it comes to the algorithm to calculate whether IMG is presentational or not, then I have suggested how it should look in my 'Validity map for <img>': http://lists.w3.org/Archives/Public/public-html/2011Mar/0750 Two examples from that algorithm: * If IMG has non-empty @title, then AT should consider the IMG as non-presentational, regardless of @alt's value. * Ditto if IMG has @aria-labelledby - regardless of @alt's value. -- Configure bugmail: http://www.w3.org/Bugs/Public/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.Received on Tuesday, 3 May 2011 13:01:34 UTC
