Hi Chaals, you wrote: "Not necessarily. There is a deep issue I have with ARIA, about claiming that it is only for "assistive technology" and thereby *assuming* it won't be implemented or wanted as native functionality in browsers. I think this assumption is demonstrably wrong (among other things a lot of aria functionality was developed to run directly in browsers)." As stated in the WAI-ARIA spec and re-iterated in the HTML5 spec (against hixie's wishes, so not in HTML the living standard http://www.whatwg.org/specs/web-apps/current-work/multipage/elements.html#wai-aria ) "The WAI-ARIA specification neither requires or forbids user agents from enhancing native presentation and interaction behaviors on the basis of WAI- ARIA markup. Even mainstream user agents might choose to expose metadata or navigational features directly or via user-installed extensions; for example, exposing required form fields or landmark navigation. User agents are encouraged to maximize their usefulness to users, including users without disabilities." source:http://dev.w3.org/html5/spec/wai-aria.html#wai-aria best regards Stevef On 15 March 2012 14:50, Charles McCathieNevile <chaals@opera.com> wrote: > On Thu, 15 Mar 2012 12:27:53 +0100, Silvia Pfeiffer < > silviapfeiffer1@gmail.com> wrote: > > This is a good discussion. >> > > Yep. > > > On Thu, Mar 15, 2012 at 9:01 PM, Sean Hayes <Sean.Hayes@microsoft.com> >> wrote: >> >>> I am not sure that these are necessarily the same thing at all.
