WCAG 2 includes D-links too. Though they are no referred to as 'description links' and they have also jumped away from usign that visible (or even hidden) "D". Take a look at WCAG technique G73: http://www.w3.org/TR/WCAG20-HTML-TECHS/G73.html#G73-description > There is no indication that we will not see a return to this type of behaviour: > in fact, as examples from the wild show us, the hiding technique is alive and > well, but now uses CSS to place the link off-screen. As a result, these types > of techniques then impact on requirement 2: G73 suggests hiding the description by wrapping an invisible (1px wide) <img> in a link - I wonder which ARIA @role to use on that <img> ... G73 also suggest using the caption as a caption element and descriibing the purpose of the link in the @title attribute. (But according to Steve, screenreader users don't use the @title attribute - http://www.paciellogroup.com/resources/articles/WE05/forms.html.) > " 2.

Indeed. Therefore I don't understand why you don't come out in support of @rel="longdesc". As G73 makes clear: *even* when one can use a visible link (as a caption), there is still necessary to make clear that that it is a link to a long description. -- Configure bugmail: http://www.w3.org/Bugs/Public/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the QA contact for the bug.
