Hi, It seems that the WAI ARIA requires that host languages allow authors to express a number of meaningless combinations, for instance: * Specifying a role="" on an element whose purpose is another role, e.g. WAI-ARIA appears to require host languages to allow the following: <input type="checkbox" role="textbox"> * Specifying a state or property on an element in a way that contradicts host language semantics, e.g. WAI-ARIA appears to require host languages to allow the following: <input type="checkbox" checked="checked" aria-checked="false"> I would like to request that host languages be able to state which roles elements in the host language map to, and be able to forbid authors from contradicting these roles. Similarly, I'd like to request that host languages be able to define certain states and proprties that host language attributes map to, with the corresponding ability to forbid authors from contradicting these implicit states and properties. Specifically, it is the following bullet point in section 6.1.1. Role Attribute: * The appearance of the name literal of any concrete ARIA role (see section 7.3.2) as one of these substrings MUST NOT in and of itself make the attribute value illegal in the host-language syntax ...to which I object.
