Steve,

Are you aware of any validators checking this?

There are normative authoring requirements around this:

Authors MUST use lowercase ASCII letters<https://html.spec.whatwg.org/multipage/infrastructure.html#lowercase-ascii-letters> for all role token values and any state or property attributes (aria-*) whose values are defined as tokens<https://www.w3.org/TR/wai-aria-1.1/#propcharacteristic_value>.

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).

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
