Well I think you would need to give IA2 implementers *very* clear guidelines on how to use these states and how to map to the APIs and concepts that they use. For example my view that ENABLED means the user can interact (and implies a non-greyed visual style) comes from using EnableWindow() to control a controls ability to respond to the user via input device events (well mouse and keyboard). There's no concept of SENSITIVE there so I'd need to remember to add those semantics if required for IA2.
Can we think of concrete examples in GTK or other widget sets. Or are we trying to model something that may be theoretically possible but is never actually realised?
