To document is not to spec but to show data about how the reality looks like.

I see no differences between me and the A11Y implementation guide here. > as to @hidden, the 'HTML to Platform Accessibility APIs > Implementation Guide' has not *yet* documented the mappings And my assumption was - and is - that this is because they are hard to document - perhaps because there is nothing to document. It seems to me that, at least for now, @hidden simply maps to style="display:none", and nothing more. Do you have data for any other conclusion? We have heard that Firefox has started to implement what ISSUE-204 is about. So what does Firefox do if the @aria-describedby points to a hidden section which *also* has aria-hidden="true" set? I have not tested that exact example, but based on the tests I have don, I don't think it works. If so, then HTML5 is wrong - or at least not exact enough. > [1] http://www.w3.org/WAI/PF/aria-implementation/#mapping_state-property -- leif halvard silli
