Indeed it is not just text that needs to be clear and simple. I have argued
before (and will again) that we need to have more information on how to make
graphics accessible (having good contrast in colours is a start, but only a

I agree that we need to be careful about how much importance we attach to a
couple of rough-draft tests - they can give us some ideas, but could be badly
designed for any number of reasons. However, we need to start somewhere, and
this test, like Kynn's test, can give us some data that we can think about
how to use. Obviously, more testing, and carefully designed testing, is
