4610  *   add / delete: all types that may be added or deleted must use an
4611  * X-ORDERED attributeType for their RDN. Adding and deleting entries
4612  * should automatically renumber the index of any siblings as needed,
4613  * so that no gaps in the numbering sequence exist after the add/delete
4614  * is completed.
4615  *   What can be added:
4616  *     schema objects
4617  *     backend objects for backend-specific config directives
4618  *     database objects
4619  *     overlay objects
4620  *
4621  *   delete: probably no support this time around.
4622  *
4623  *   modrdn: generally not done. Will be invoked automatically by add/
4624  * delete to update numbering sequence. Perform as an explicit operation
4625  * so that the renumbering effect may be replicated. Subtree rename must
4626  * be supported, since renumbering a database will affect all its child
4627  * overlays.
4628  *
4629  *  modify: must be fully supported.
