AW: Proposal for next Questionnaire (was: Re: A question about Step 4.b: Use WCAG 2.0 Techniques Where Possible)

Hi all,

I still have reservations with the whole Step 4b, as already stated and suggest to delete this step and provide a section "relevance of techniques and testing procedures" instead which of course must be conform to WCAG2.

Kerstin: I also think that we should provide some guidance, which could also include a section on "how not to use the techniques" in an evaluation

Kerstin: I also think that the testing procedures are giving guidance for evaluations, but:

> While the Sufficient Techniques
> are informative only, their examples and test procedures should be used
> as guidance and referenced when rating web content."

is unclear. First the question is what "guidance" means. Apart from it would it would be contrary to what is written in WCAG 2.0: " Test procedures do not, however, imply success or failure beyond the particular technique. In particular, test procedures for individual techniques should not be taken as test procedures for the WCAG 2.0 success criteria overall."

Kerstin: We would also in opinion rewrite WCAG 2.0 and I believe this will lead to confusion.
