If you were evaluating a page for compliance to WCAG2 and the page was not using a sufficient technique and not using a common failure you still rate the page as pass, fail or possibly even cannottell. A human evaluator with expertise in accessibility testing would be expected to always rate the page as pass or fail. If these human evaluators found compliance as "cannot tell" then it would mean the guideline was untestable. If a machine were to evaluate a web page it would be quite acceptable to find compliance as "cannot tell". The machine could also return a result of fail but I don't think there are any HTML pages that a machine could return a result of pass. EARL is used to express test results not details about the tests themselves. We still don't have a test description language. Cheers, Chris
