According to the note from the PFWG (not official yet, just a
summarization of what they felt was likely at the time), inherent
semantics win over ARIA states and properties (for example, @checked
wins over @aria-checked if both are specified on an <input
type=checkbox>), but lose to ARIA roles.  Strong inherent semantics
still lose to ARIA roles, but should trigger conformance errors when

ATs and such should respond to ARIA by those criteria.
