Well, *some* answer was required; I simply chose to imply "yes" and
make the statement more precise.  BTW, precision is a good habit for
software designers, so while you're welcome to practice it on me,
please consider being precise in all your communications, writing
*and* reading!<wink>

Oh, and I just noticed that it's not necessarily the case that the
later rule undoes the previous one.  It *might* be a good idea to have
a "first match wins" interface rather than a "last match wins" one.
