RE: Regarding AccName and case sensitivity of roles and attribute values

From my humble knowledge of the past group decisions, it IS strict and SHOULD be accepted by User Agents if correct.
User agents may apply internal heuristics to work around and therefore uppercase has no effect in practice.

But I think even some validators out there check already attribute case (Must look for examples here).

Subject: Regarding AccName and case sensitivity of roles and attribute values

Hi,
Does anyone know how strict the case requirement is for ARIA roles and supporting attributes?

Since AccName changes depending on specific roles when present, I need to know if certain usages are automatically ignored or if they should be supported, such as if role="tablist" is correct, but role="TabList" is not. According to the ARIA spec, the second is not valid.

Please let me know your thoughts.

Thanks,
Bryan
