Catalog.nsf aka Database Catalog has quite a bit of useful information on the "NoteFile" document:
ACL, Policy document (aka: Help doc) etc
Sadly, ACL information gets truncated (long heiarchies) and renders this information quite useless.
Most notably, the "Link to database Policy document" is a link to the database's Help->About document.
A link is of no use when the user is not authorized to access the database.
Ideally, I'd like to see the catalog entry display the database Help->About document the way it used to;
pulling in the about document data into the catalog entry as opposed to a link to it.
