[Zope-dev] ZCatalog API

Hi list, as I'm not very familiar with the internals of ZCatalog I have a question to all you API experts: Why does ZCatalog.py (under Zope 2.4.1) specify a 'addIndex' permission for a method called 'manage_delIndexes' although there is no such method? The only method I could find to delete Indexes is 'manage_deleteIndex'. Can anyone comment on this? TIA Erich
