Where is the processing model for that defined? HTML4 seems to suggest  
that scope= can be used instead of headers=, not in conjunction. It  
doesn't really define what UAs should do when they encounter a TD that  
uses both, nor does it seem to define what headers="" (empty string value)  
means or headers="x" where x is either a non-existant ID or an ID on an  
element that is not TH or is TH but is not part of the table. How do  
screen readers support all those various cases today? Has this been tested  
by someone?
