Hi Rich,
This is certainly how Firefox exposes it, except that Firefox also
exposes the checkable state, which is a related (but separate) issue.
This option certainly makes sense.
The alternative is to use a role of button and introduce a pressable
state or document that the checkable state on buttons actually means
pressable.
I don't mind which from a principle standpoint, but it would seem the
former will have less impact, given that Firefox is already doing it.

Jamie,
In ARIA you apply aria-pressed="true" or aria-pressed="false" it will
become a toggle button. From the implementation guide should we say
something about the pressed state.
IAccessible2: If _aria-pressed_
<http://www.w3.org/TR/2014/PR-wai-aria-20140206/states_and_properties#aria-pressed>
is
not *undefined*, it *SHOULD* be exposed as IA2_ROLE_TOGGLE_BUTTON
IOW if you are ever to use a pressed state then you should change the
role to IA2_ROLE_TOGGLE_BUTTON
Cheers,

Further to this, the IA2 spec recommends using ROLE_SYSTEM_PUSHBUTTON.
The problem with this is that it's not possible to tell whether the
button can be toggled when it is not pressed. That is, you can't tell
whether it's just a normal button that can't be toggled or whether it's
a button that can be toggled (pressed or not pressed).
