That the document referred to as "HTML5" currently disallows things which works in ARIA, is well known: http://www.paciellogroup.com/blog/?p=585 But in which way are we talking about 'works' when it comes to using ARIA to link to @hidden elements? ARIA is probably silent about <noscript> as well. But what happens, in a script enabled Firefox browser, if aria-describedby points to a <noscript> element? Pointing to <noscript> perhaps works. (???) But what if it points to a <script> or a <style> element? Hey, you may even let aria-describedby point to another IMG element - or even the very same IMG element! That it isn't forbidden – and that it works, if we only look at the linkage technicalities – does not mean that user agents are required to start reading the script or the style sheet. "Works" could simply mean that user agent tells the user that, sorry, that element is hidden and therefore will not be read. -- leif halvard silli
