Hi Léonie,

From http://www.w3.org/TR/WCAG/#conformance-claims - "Conformance is not possible at a particular level if any page in the process does not conform at that level or better".

And, as an additional component of the conformance claim "A list of success criteria beyond the level of conformance claimed that have been met. This information should be provided in a form that users can use, preferably machine-readable metadata."

So, I would suggest that for our purposes (those of evaluating the whole site) this would mean - making a level AA conformance claim for all pages in the sample (website).  If required by the website owner (or other) it could be provided along with a list of urls for the web pages on which the additional AAA Success Criteria have been achieved.  

If we were not looking at the whole site separate AA and AAA claims for the relevant pages would probably be the way to go.  I should add, that a AAA conformance claim could only be made for the pages which were AAA conformant - ruling out, in my opinion, a AAA with exceptions type claim.

Let me know what you think.

All the best 

Alistair

I wonder what that will mean for the practical acceptance of the methodology. Will it come to be derided as academic, as impossibly demanding? Who then is the customer of a (sorry, chap) refused seal of conformance who bows to gracefully accept the list of flaws to rectify? Just wondering...it just strikes me as slightly surreal...
