4632  *   add / delete: all types that may be added or deleted must use an
4633  * X-ORDERED attributeType for their RDN. Adding and deleting entries
4634  * should automatically renumber the index of any siblings as needed,
4635  * so that no gaps in the numbering sequence exist after the add/delete
4636  * is completed.
4637  *   What can be added:
4638  *     schema objects
4639  *     backend objects for backend-specific config directives
4640  *     database objects
4641  *     overlay objects
4642  *
4643  *   delete: probably no support this time around.
4644  *
4645  *   modrdn: generally not done. Will be invoked automatically by add/
4646  * delete to update numbering sequence. Perform as an explicit operation
4647  * so that the renumbering effect may be replicated. Subtree rename must
4648  * be supported, since renumbering a database will affect all its child
4649  * overlays.
4650  *
