7540  *   add / delete: all types that may be added or deleted must use an
7541  * X-ORDERED attributeType for their RDN. Adding and deleting entries
7542  * should automatically renumber the index of any siblings as needed,
7543  * so that no gaps in the numbering sequence exist after the add/delete
7544  * is completed.
7545  *   What can be added:
7546  *     schema objects
7547  *     backend objects for backend-specific config directives
7548  *     database objects
7549  *     overlay objects
7550  *
7551  *   delete: probably no support this time around.
7552  *
7553  *   modrdn: generally not done. Will be invoked automatically by add/
7554  * delete to update numbering sequence. Perform as an explicit operation
7555  * so that the renumbering effect may be replicated. Subtree rename must
7556  * be supported, since renumbering a database will affect all its child
7557  * overlays.
