Why do you want to do this?

It is possible to remove this protection by removing the id of the object 
that is protected from a list found on the root object, called 
_reserved_names. You could use the monitor client to step into your zope 
process, and do something like this:

   import Zope
   app=Zope.app()
   app._reserved_names

and the last command should show a tuple with all protected ids in it. If 
you set _reserved_names to a tuple that doesn't include the ids you want to 
be able to delete, the protection is gone. The command sequence:

   app._reserved_names = ()
   get_transaction().commit()

will remove all objects from this protection against deletion. Don't forget 
the commit(), this will save all changes made in the transaction.
