Another problem with the algorithm in HTML4 is that it suggests it should  
only be taken into account when there's no scope= or headers= information  
in the table. (It's not augmentative.)

Another problem, which I think can only be worked around with headers=""  
(given that headers is not augmentative, I'm not sure about that) is that  
the rowgroup headers should not get the col headers. "Location" etc. is  
not an appropriate header for "Day 1 ..." etc. Although maybe you could  
add an additional requirement that a header cell for a given cell needs to  
span the same columns (or more) for it to become a header cell for that  
cell (also, not same amount of columns, the same columns). This would also  
help with the Thesis example from Henri.
