Seems like we really want an end result where the system automatically updates
links on an as-needed basis. What about this... if the called for link fails to
turn up the referenced document, the database fails to a "link fixer" document.
(One can configure this in DOMCFG.NSF.)
The link fixer document tries to fix the link if possible, otherwise it deletes
the link, and concludes by giving the user something appropriate, either the
found document or some other suitable message.
