So does this "Each WCAG 2.0 Test Sample must be linked to exactly one 
WCAG 2.0 technique or failure, .. " applies?

If we mean that an "anti-technique" test sample needs to link to the 
technique (the way I have developed the committed tests) I think we need 
to clarify this in document. (Otherwise make techniques optional?? - 
dont think..)
