The distinction described in that email is probably too subtle for  
casual authors to get right. Do existing AT implementations make the  
distinction? How is the distinction conveyed to the user?

I'd go with something simpler: Cells that the author wants reported  
when the user queries another cell for its headers should be marked up  
as <th>. Is it common that the author wouldn't want these cells to be  
styled distinctly in the visual presentation? And if it is common, is  
it better to solve the mismatch by overriding associations or by  
overriding visual style?
