Re: Finding complete processes

Hi,

 From a practical point of view, even if external resources are not  
under the control of the site owner, they have been chosen to be  
included and are therefore an integral part of the process. They  
cannot be ignored, otherwise the process would not be complete. Either  
the entire process is excluded or it must be evaluated in its entirety.

In many cases, site owners have a choice regarding the external  
resources they use. Take, for example, a shop system integrated into a  
site. Some systems will be more accessible than others. Some have  
templates that can be customised to make them more accessible. So a  
result of an evaluation might be that a sote owner has to change to a  
more accessible external service or customise it, if possible.

In general, I agree with Alistair that a specific identification of  
scope is useful. A site may have several sections, some that conform  
(even to different levels), others that do not (yet) conform. As long  
as the claim makes this explicit I think it is useful to differentiate  
even within one website. The WCAG "Required Components of a  
Conformance Claim" are useful for that.

Detlev
