4611  *   add / delete: all types that may be added or deleted must use an
4612  * X-ORDERED attributeType for their RDN. Adding and deleting entries
4613  * should automatically renumber the index of any siblings as needed,
4614  * so that no gaps in the numbering sequence exist after the add/delete
4615  * is completed.
4616  *   What can be added:
4617  *     schema objects
4618  *     backend objects for backend-specific config directives
4619  *     database objects
4620  *     overlay objects
4621  *
4622  *   delete: probably no support this time around.
4623  *
4624  *   modrdn: generally not done. Will be invoked automatically by add/
4625  * delete to update numbering sequence. Perform as an explicit operation
4626  * so that the renumbering effect may be replicated. Subtree rename must
4627  * be supported, since renumbering a database will affect all its child
4628  * overlays.
4629  *
4630  *  modify: must be fully supported.
