[Zope] ObjectManager and method doc strings

In order to do things like: http://192.168.1.190:10080/tssadmin/objectIds and see the object ids, OFS/ObjectManager.py needs doc strings in the methods that we want to call. It seems that the Zope distribution code doesn't have these doc strings for methods like objectIds, objectItems etc. Is this a security feature or is there another (preferred) way to execute methods like objectIds?
