Hi Kerstin,

This is an excellent article, many thanks for making us all aware of it.
It acknowledges the role of tester subjectivity in assessing the 
severity of barriers (a role that we all want to reduce as much as 
possible). In my view, the method Roger Hudson suggests is a step beyond 
the problems of settling for either pass or fail per success criteria 
and page since it recognises that it is the combination of incidence and 
severity of bvarriers that determines impact, and tries to reflect this 
real impact in a pragmatic way that helps prioritising remedial work. I 
like the approach a lot. How that can be mapped on a WCAG conformance 
scheme is not clear yet, however...and many aspects such as page 
sampling or the inclusion of processes and dynamic content are not 
explicitly covered. Still, it looks like a well reasoned approach.

Detlev
