Thanks again.

As for your suggestion about DoV - we will probably see what we capture in 
QA Spec and then figure out whether we need to say more.  One of the 
reasons I'm favoring a Note, is that this may be of interest to people, 
outside the scope of QA Spec.  However, we plan to solicit other opinions 
on the usefulness of DoV.
