Re: Accessibility Statements:
Since conformance claims are already covered (as optional!) in WCAG  
2.0 itself, with required and optional components, I see no harm in  
dropping it in the current draft or WCAG-EM. I fully agree with Peter  
that we should focus on the trickier aspects of evaluating web  
applications (or, in simpler cases, web pages that have different  
states invoked by the user after the initial loading).

Including states and processes:
The problem is that prescriptions towards selecting common processes  
and states to be included in the sample are hard to put in a way that  
they would make sense for all forseeable applications of WCAG-EM. We  
may deal with a simple lightbox (here, "page state' is fine) or with  
the equivalent of a complex decision tree the consequent states of  
which may depend on user input (say, has a credit card number provided  
by the user been verified or not). In suggesting 'page states' I was  
aiming at a level of abstraction which might on a basic level apply to  
both the simple case (a lightbox) and the most complex - after all,  
any complex interaction might be captured as a linked series of page  
states (sometimes leading to another page), if I am not mistaken.

The big problem is then how to capture and document in the sample the  
states of more complex processes without incrementing the sample size  
exponentially and turning the evaluation into a nightmare (it can  
already be very time-consuming to restore previous states when looking  
at straightforward processes - now think of dozens of process  
variants...). The problem is also specifying (without being overly  
prescriptive) what branches of the process space the evaluator should  
include if there are simply too many to cover them all (cue the  
distinction core/common vs. ancillary).

I may try to come up with some (very tentative) wording for others to  
improve or reject. I am pretty sure it won't be easy...

Regards,
Detlev
