Nothing. Just because the Zope management interface uses a hierarchical structure, doesn't mean that every object cannot be referenced more then once.
Thats correct. And I believe some objects are in fact referenced more than once. But be careful if you are using objects that do not conform to Zope management interface. I had one bad experience where I created a lot of instances of a custom persistent object and added them onto standard Zope objects using an external method. Later some bugs in my object source corrupted the whole ZODB. Jim Fulton pointed politely that I souldn't do such bad things, but I think he was just too polite. As it turned out you didn't have such bad thinks in mind. Pavlos
