6515  *   add / delete: all types that may be added or deleted must use an
6516  * X-ORDERED attributeType for their RDN. Adding and deleting entries
6517  * should automatically renumber the index of any siblings as needed,
6518  * so that no gaps in the numbering sequence exist after the add/delete
6519  * is completed.
6520  *   What can be added:
6521  *     schema objects
6522  *     backend objects for backend-specific config directives
6523  *     database objects
6524  *     overlay objects
6525  *
6526  *   delete: probably no support this time around.
6527  *
6528  *   modrdn: generally not done. Will be invoked automatically by add/
6529  * delete to update numbering sequence. Perform as an explicit operation
6530  * so that the renumbering effect may be replicated. Subtree rename must
6531  * be supported, since renumbering a database will affect all its child
6532  * overlays.
6533  *
6534  *  modify: must be fully supported.
