Hello all,

I think there shouldn't be a problem talking about "objectivity" when we deal with normalization. 

After all, standards should be measurable and therefore, objective. If we feel better using "agreed interpretations" it's all fine by me because I can relate to that as well. 

But one way or another, we'll have to come up with these "agreed interpretations" and that, my friends, based on 10 years or so of watching divergent accessibility experts expressing different opinions on the subject, leads me to think it will not be easy! ;p

It could probably mean going through all the sufficient techniques and common failures and, for each and every one of them, come up with a list of "agreed interpretations" that all actually work out when common tests are being performed to measure the compliance to a specific success criteria.

Looking forward to *very interesting discussions* here... =)

Best,

/Denis

I think "agreed interpretation" hits it nicely because there is the community element in it which is quite central to WCAG 2.0 (think of defining accessibility support)
