"Accessibility features"

During the call last Thursday, somebody complained that my rewrite of 
1.3 to require the use of accessibility features of a technology was 
ambiguous. Which technology? And what if there aren't any for that 
technology?

If this is such a contentious concept, why is it already in 4.2?

If memory serves, WAI has spent a lot of time documenting the 
accessibility features of various technologies. None of this is a 
crazy new concept.
