No problem.

Yes, I guess so. I saw text bit in version b which spoke about 
other users than speech and braille users, and I was not certain I 
agreed to that.

I feel that it addresses directly in the code the juxtaposing of 
summary and <caption> that I think is needed. The <caption> 
element is one that the author will often be working with all the 
time - it is the place where he attributes meaning to the entire 
table. The title might often be the final touch. This is also 
natural moment for when to add info about the table struture.

Wheras when the author starts with the <table> element, he might 
not have much clue about what the content will be. Most authors 
considers <table> only a kind of container element - they do not 
consider it any more semantic than <div>. In order to add anything 
inside @summary, one must either know the table structure before 
one creates the table, or one must go back to the <table> element 
and add @summary once it is finished.

The title - aka caption - however, one works with through out the 
table creation process, I think.

And, if one is running the table through some acessibilty checker 
which tells the author to add a caption@summary, the author might 
in the same go be reminded about adding caption conten as well.

(And likewise, if one has added a caption, and the checker asks 
for a summary, then I think many will find it naturally to add it 
to the caption@summary.)

I describe some of those above.  One should add the summary when 
one knows the entire table structure. When the author adds the 
caption is also the moment when he thinks about the structure. 
While when @summary is part of table, then the whole thing become 
more of a hard to understand accessibility burdon. (I hope this 
was answered what you asked a litle bit, at least.)
