That's actually option B ;-)

The downside of a technique-oriented approach (option B) is that it 
does not make much sense when creating test samples that do not map to 
a technique documented in WCAG (we do that often in BenToWeb) or when 
creating test samples for a set of guidelines that does not link to 
techniques (I assume that's Shadi's point).

I assume this actually refers to option C ("techniques" element inside 
the "location" element). The repetition of the technique for each 
location is a clear downside. On the other hand, as Carlos Velasco 
pointed out, we could require that test samples are "atomic" in the 
sense that each sample contains only one occurrence of the failure or 
technique, hence avoiding repetition of the technique.

Any other thoughts on this?
