It seems to me these don't exactly match any existing ARIA role, but  
at least some of them should be treated as having native semantics. In  
some cases, minting a new ARIA role would not make sense. For example,  
there's no way to replicate the effects of <input type=file> with a  
different element, so creating a new role just for the sake of mapping  
would not be a useful effort.

Upon rereading the original statement from PFWG on ARIA  
integration[1], it's not entirely clear to me if elements with "strong  
native semantics" need to map to an ARIA role. A clarification from  
PFWG would be greatly appreciated.

Similarly, it seems like some attributes that create "implicit ARIA  
semantics" don't map in a clear one-to-one way to ARIA properties or  
states. It would be good to still avoid conflicting markup even if the  
native HTML feature can't be cast exactly in ARIA terms. I believe  
that was the root of most of Ian's other questions. Again, input from  
PFWG would be greatly appreciated.

Regards,
Maciej
