Hi Martijn,

I think the separation by disability as outlined below would not meet 
WCAG 2.0. I think we need to clarify that this is not the intend.

This was also an issue raised by Samuel and logged as comment #97:

I think that Elle's proposal of using scenarios and tasks seems to fit 
well into this section. The idea is precisely not to forget about, say 
visual keyboard users and other situations that are frequently missed.
