Hi Leif, Thanks for your hard work on this. Due to the HTML Chairs delay on ISSUE-30 I have asked Sam, Paul and Maciej to open a new Issue (ISSUE-206) for expanding longdesc to other elements after ISSUE-30 is decided: http://lists.w3.org/Archives/Public/public-html-a11y/2012Mar/0209.html http://lists.w3.org/Archives/Public/public-html-a11y/2012Mar/0210.html http://lists.w3.org/Archives/Public/public-html-a11y/2012Mar/0212.html I await their reply of whether they will open an ISSUE-206 (if ISSUE-30 results in including longdesc in the spec). Hopefully they will decide this in a timely manner. Janina, this would be the two step process that you spoke of last week.
