6898  *   add / delete: all types that may be added or deleted must use an
6899  * X-ORDERED attributeType for their RDN. Adding and deleting entries
6900  * should automatically renumber the index of any siblings as needed,
6901  * so that no gaps in the numbering sequence exist after the add/delete
6902  * is completed.
6903  *   What can be added:
6904  *     schema objects
6905  *     backend objects for backend-specific config directives
6906  *     database objects
6907  *     overlay objects
6908  *
6909  *   delete: probably no support this time around.
6910  *
6911  *   modrdn: generally not done. Will be invoked automatically by add/
6912  * delete to update numbering sequence. Perform as an explicit operation
6913  * so that the renumbering effect may be replicated. Subtree rename must
6914  * be supported, since renumbering a database will affect all its child
6915  * overlays.
6916  *
