XHTML2 namespace not required for ARIA roles

[Becky Gibson]

consider updating wai functions for ARIA to not use Xhtml2 namespaces for roles - it is not needed in Firefox2 and will assist in future ARIA support in operat

from Aaron: you can do: <div role="wairole:menuitem" aaa:checked="true"> and it will work in ff2

the checked attribute needs to be set dynamically for ff2, but role doesn't

and now for ff3, you can just do <div role="menuitem" aria-checked="true"> right in the html but the old way still works as well

I propose adding the following functions to dijit.wai:

• setRole()
• setState()
• getRole()
• getState()
• removeRole()
• removeState()

(or setWaiRole() and so on, or setARIARole() and so on)

I would make waiRole, waiState, setAttr, getAttr, and removeAttr private. This will allow us to implement different behaviour on different browsers, such as on FF2 and FF3. I also think it makes the API a little clearer and easier to use.

[Becky Gibson]

yes, agreed. It was nice having one function to set both role and state but we will likely need different implementations in different browsers going forward and it would be better to set the api now. However, this is an api change and we need to run it by Bill.

(In [10791]) Modified the API for setting ARIA roles and states. Implemented support for recent changes in the ARIA specification. Fixes #4556: XHTML2 namespace not required for ARIA roles.
