Well, rather as with GRIDDL, the standards that allow the use of role in 
HTML are not yet finalized:

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).

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:


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.
