hi jonas, > Like I said, this was a patch to the code that exposes content to AT > users. how does it do so? what mecahnism does it use to provide access /point to to structured content only for AT users. But having read further i do think you are correct in your interpretation from the aria implementaion guide: "Note that aria-describedby may reference structured or interactive information where users would want to be able to navigate to different sections of content. User agents MAY provide a way for the user to navigate to structured information referenced by aria-describedby and assistive technology SHOULD provide such a method." http://www.w3.org/TR/wai-aria-implementation/#mapping_additional_relations still the problem being that there is no requirment on either browsers or AT to do so and as implemented none do it. So in regards to the leifs original issue with the authoring guide, I still think he is correct and that until such times that aria-describedby is implemented in a way that matches the authoring advice it is misleading and inaccurate. regards stevef On 22 April 2011 23:08, Jonas Sicking <jonas@sicking.cc> wrote: > On Fri, Apr 22, 2011 at 2:25 PM, Steve Faulkner > <faulkner.steve@gmail.com> wrote: >> Hi Jonas >> >>> I wrote a patch in about 30 minutes to do so. >> >> Interesting, so how is this behaviour exposed to users? >> >> Feedback received from the NVDA developers was that they want UI in the browser. > > Like I said, this was a patch to the code that exposes content to AT > users.
