What do the specs say about the scope of a non-permalink guid?
I recently struck these two feeds

    http://rss.weather.com.au/sa/adelaide
    http://rss.weather.com.au/nt/darwin

which have the same guid (non-permalink), but different content.  (They
update every 15 minutes or something, the guid changes with such
updates, but to the same new value for the two locations.)

It made me suspect non-permalink guid is only for the given feed url,
apparently not univeral nor even throughout the given server.  (I jigged
up Message-ID from my rss2leafnode program accordingly, but couldn't
find the right bit of the specs to confirm or deny.)
