These few lines are, to me. the most enlightening comment 
regarding the purpose of @summary that I have read. Especially 
that about the structure of the table. Of course, a user that is 
able to see the rendered document, does not need that the text is 
poluted by a description of things he can allready see. Also, 
there are many cases when the table and cell borders are hidden, 
so that even the sighter one cannot perceive that it is a table - 
unless he disable author CSS. Yet, the screen reader user, will be 
informed that it is a table and would benefit from a description 
the structure.

It seems to me that, as long as HTML 5 contains description for 
filling out an @alt, it should also describe how to fill out @summary.
