AW: New version Methodology

Hi all,

sorry. I also disagree with item 9.

As I understood the discussion there wasn't an agreement about, that the
claim always sets the scope. As I remember the discussion we found some
cases for exceptions (Shadi mentioned). Item 9 is - as already mentioned in
the note - not conform with WCAG conformance statement. Which would mean
that an evaluation like this wouldn't be valid.
