ARIA roles for hit regions

Hi Ian,

In your proposed spec text for hit regions [1] you state the following
role (default null) An ARIA role for accessibility tools to use to
determine how to represent this region, if there is no control.
Can you provide some examples of how this would be used? ie use cases.
you appear to suggest that structural roles (non control roles) can be
used, yet many non control roles require states and properties to be
assigned to be meaningful, yet there is no method provided to assign them,
how will that work?
As ARIA does not provide roles for all roles defined in the various acc
API's how do you propose that any gaps be filled?
