ACTION-1392: Add a switch role to ARIA 1.1

Hi all.

Proposed text, NOT yet committed, for the new "switch" role follows. Any
changes?

<quote>
A toggleable input that has two possible values: true or false.

The aria-checked attribute of a switch indicates whether the input is on
(true) or off (false). The mixed value is not supported, and user agents
must treat a mixed value as equivalent to false for this role.

NOTE
A switch provides approximately the same functionality as a checkbox and
toggleable button, but makes it possible for assistive technologies to
present the widget in a fashion consistent with its on-screen appearance.

In addition, under the definition for aria-checked, the switch role was
added to the can't-be-mixed language there so that the new text reads:

<quote>
The mixed value is not supported on radio, menuitemradio, switch or any
element that inherits from these in the taxonomy, and user agents must
treat a mixed value as equivalent to false for those roles.
