4907 /* Notes:
4908  *   add / delete: all types that may be added or deleted must use an
4909  * X-ORDERED attributeType for their RDN. Adding and deleting entries
4910  * should automatically renumber the index of any siblings as needed,
4911  * so that no gaps in the numbering sequence exist after the add/delete
4912  * is completed.
4913  *   What can be added:
4914  *     schema objects
4915  *     backend objects for backend-specific config directives
4916  *     database objects
4917  *     overlay objects
4918  *
4919  *   delete: probably no support this time around.
4920  *
4921  *   modrdn: generally not done. Will be invoked automatically by add/
4922  * delete to update numbering sequence. Perform as an explicit operation
4923  * so that the renumbering effect may be replicated. Subtree rename must
4924  * be supported, since renumbering a database will affect all its child
4925  * overlays.
4926  *
4927  *  modify: must be fully supported.
