Re: role = 'img'

Hi Wilco,
I'm thinking of a selector like [role~="img"]. This would search for "img"
in the role string. It would work with your case. That is about as complex
as attribute selectors can get. For example we cannot look for
[style.font-family ~="..."] in CSS. So we need a good top level
deterministic attribute for selection, role="... img" would work.

Best, Wayne
