Well, rather as with GRIDDL, the standards that allow the use of role in HTML are not yet finalized: http://www.w3.org/TR/grddl/ http://www.w3.org/WAI/PF/adaptable/HTML4/ > I have no knowledge of those applications, but they could obviously > continue to work as they do today. It would be better to standardize how WAI roles work, given their widespread support from the AT community (Freedom Scientific, GW-Micro, NVDA, Sun/GNOME/Orca, Fire Vox, OatSoft). > Furthermore they could start using the class attribute, if appropriate. The draft I refer to above actually uses the class attribute like this: <div class="axs checkbox"> Where axs is acting as a namespace (in the generic, non-XML sense). For backwards compatibility, a script converts that into a role in the XHTML2 namespace. But there are major limitation to this technique: http://www.w3.org/WAI/PF/adaptable/HTML4/embedding-20061212.html#limitations The most cogent one is: "Each HTML element can only be associated with a single role." I haven't yet worked out why that limitation exists, however. -- Benjamin Hawkes-Lewis
