Target Milestone: ---
The optimum region is expressed with color in browsers, which means that this
feature cannot currently be used without violating WCAG 1.4.1 Use of Color
We need a way to express the optimum, sub-optimum, sub-sub-optimum via
accessibility APIs.
In UIA, we propose to do this by adding the Value pattern in addition to the
specified RangeValue pattern. The numberic value of the meter would continue
to be stored in RangeValue:Value and the optimum state would be stored in
Value:Value as Good, Fair, Poor.
