4673  *   add / delete: all types that may be added or deleted must use an

4675  * should automatically renumber the index of any siblings as needed,
4676  * so that no gaps in the numbering sequence exist after the add/delete
4677  * is completed.
4678  *   What can be added:
4679  *     schema objects
4680  *     backend objects for backend-specific config directives
4681  *     database objects
4682  *     overlay objects
4683  *
4684  *   delete: probably no support this time around.
4685  *
4686  *   modrdn: generally not done. Will be invoked automatically by add/
4687  * delete to update numbering sequence. Perform as an explicit operation
4688  * so that the renumbering effect may be replicated. Subtree rename must
4689  * be supported, since renumbering a database will affect all its child
4690  * overlays.
