Hi Steve,

It's from r7029, which is one of the revisions my CP aims to restore to
the W3C version of the spec.

Each hit region has an associated control, which is either an element or
an unbacked region description. You pass in the control when you call
addHitRegion(). Is this unclear in the spec text?

We should make the easy things easy and the hard things possible.
Allowing hit regions to be associated with either unbacked region
descriptions or elements allows for this: if you have a complex thing
which requires WAI-ARIA states and properties to describe, use an
element. If not, use an unbacked region description.
