I don't have an example hanging around... yet. It took us so long to get
to this point that we figured that we needed to make a beta release to
declare our intentions, get feedback, etc. But you've given me an
incentive to do this necessary testing so I will cook up an example --
hopefully it'll be fairly neat -- and send it to you.

See, we are *even* prepared to help CMS :-P
