I'm sure you're puzzled because I wrote something that is truly puzzling
:). I promise that I'm not trying to do it on purpose! Conveying these
ideas over a mailing list is quite error prone.

Yes, that is correct. I'm not attempting to make a change to the current
rules regarding @about. In other words - the rules that I'm proposing
shouldn't deviate from what the APPROVED test cases generate. Regardless
of if we use Ben's rules, or Mark/my rules, the APPROVED test cases
shouldn't be affected.

Oops, you're correct. @content shouldn't set the subject. This is the
problem with authoring rules at 1am in the morning :). Again, keep in
mind that I'm not attempting to propose anything that would break the
currently approved test cases.
