Dear All, 

The concept of "100% conformance for the pages sampled" gained a reasonable level of consensus amongst EVAL TF members (6 or 7 people).  Several other ideas have seemingly gained the same group approval, but then fallen by the wayside as we've move ahead to debate something else... 

I'd like to know, what mechanism are we following to capture such ideas, and ensure that they are appear in 'black & white' in our methodology updates? 

All the best 

Alistair

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.

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...
