Description (last modified by )
Update: The checkbox and radio button implementations are being redesigned such that the user interacts with the real html inputs. This will allow dijit to adopt, for free, the browser behaviour (mouse and keyboard), of html checkbox and radio buttons. Accessibility will also be free (regular html form accessibility)
was: "The dojo radio buttons have some a11y support. The ARIA spec supports both a role of radio and ragiogroup. A single Dojo radio button should be given a role of radio and placed in the tab order of the page via tabindex=0. Dojo radio buttons that are grouped should be given the role of radiogroup and keyboard movement within a group of radios should be via the left / right arrow keys rather than the tab key. The behavior should mimic that of an HTML radio group."

Keyboard navigation fully implemented. One possible remaining loose end: tab navigation of a radio group when none are checked is currently implemented to mimic the Firefox behavior. IE behavior is different (see comment in patch) and I think non trivial to implement. A variation on the IE behavior would be easy to implement (e.g. only make the first radio in an unchecked radio group a tab stop).
It would be nice to use the browser's keyboard navigation implementation rather than mimic it ourselves but I have the feeling there are reasons we are not doing this?
Sorry I haven't attached this here earlier... I've discovered the guest account (thanks Simon).

Just noting here that we also need to add posinset and setsize aria information. I have created a test page here for seeing how these aria roles might interact with the current accessibility AT and browsers.

Since onClick is considered user overridable, I have protected (by "_" convention) the click handler implemented in Checkbox.js (in the fixonclick.diff patch). The patch also removes some value changed work I had done, as I think we will come up with different API (around normalization of state and value changes) and the choice and implementation of this API is still to be decided.
