6534  *   add / delete: all types that may be added or deleted must use an
6535  * X-ORDERED attributeType for their RDN. Adding and deleting entries
6536  * should automatically renumber the index of any siblings as needed,
6537  * so that no gaps in the numbering sequence exist after the add/delete
6538  * is completed.
6539  *   What can be added:
6540  *     schema objects
6541  *     backend objects for backend-specific config directives
6542  *     database objects
6543  *     overlay objects
6544  *
6545  *   delete: probably no support this time around.
6546  *
6547  *   modrdn: generally not done. Will be invoked automatically by add/
6548  * delete to update numbering sequence. Perform as an explicit operation
6549  * so that the renumbering effect may be replicated. Subtree rename must
6550  * be supported, since renumbering a database will affect all its child
6551  * overlays.
6552  *
