Ah, j'ai trouvé les documents en question ;)

So, if I understand it correctly, RGAA is a set of your own normative 
tests, tied to specific technologies (doing things like mandating actual 
attributes, like alt for images and summary for data tables), which you 
then match up to WCAG 2.0 success criteria? It's basically a tightly 
defined subset of possible techniques (as there may exist a theoretical 
infinite number of techniques, as long as they pass the SC) that you 
require authors to adhere to? I can understand the benefit of this for 
large-scale conformance testing, but you're really then just testing 
conformance to RGAA, not to WCAG 2.0 (as there are certainly other 
techniques, not mandated in RGAA's test appendix of the WCAG 2.0 
techniques document, which nonetheless pass the SC).

Sorry, not being difficult here, just making sure I understand the 
purpose of RGAA (and to clarify that WCAG 2.0's original intent is not 
to make any statements as to required or not required attributes...only 
the SCs matter, and the techniques are merely informative).
