One thing I find confusing about accessibility and compliance is that the WCAG publishes three different levels: AAA, AA, and A. https://www.w3.org/TR/WCAG20/#conformance-reqs
Under the law today, can websites get sued for not meeting A? AA? AAA? Or is it a self-policing kind of thing? As in, do legal departments just set their own targets based on their appetite for risk?
