And analogously: Is is conforming for a radio button to be both
checked and disabled if the whole set is not disabled? (This one is
harder to check, but anyway...)
Is it conforming to have no option that is marked selected? (I
think allowing this is safe.)
Select multiple:

How do native widgets handle this?
At least some things clearly need to be allowed to be checked/
selected and disabled at the same time. In particular, checkboxes
really need this. Allowing this in some cases but not others smacks
of trying to dictate UI policy for content authors.
It would be better to make disabled orthogonal to other UI state.
