Sure... this is no competence of WCAG Group but i have explain this for focus attention to the possibility (that is done a lot around the web also for other W3C validation and claims) that some web developer uses claim logos without having the full conformance for this logo usage. At this point, we (as W3C - i spoke also as AC Rep. for IWA/HWG) need to define some procedures for let users to have the trust of logo usage. > EARL (check me here, Wendy) has been designed to be usable in the absence of > any certification process and pre-existing trust relationship with an audit > and certification activity.

Sure but the problem is: is people able to understand claims? I see for experience that people consider a valid HTML, XHTML, CSS, WCAG 1.0 A, AA, AAA valid web sites if they see the logo put in the website...
