4964  *   add / delete: all types that may be added or deleted must use an

4966  * should automatically renumber the index of any siblings as needed,
4967  * so that no gaps in the numbering sequence exist after the add/delete
4968  * is completed.
4969  *   What can be added:
4970  *     schema objects
4971  *     backend objects for backend-specific config directives
4972  *     database objects
4973  *     overlay objects
4974  *
4975  *   delete: probably no support this time around.
4976  *
4977  *   modrdn: generally not done. Will be invoked automatically by add/
4978  * delete to update numbering sequence. Perform as an explicit operation
4979  * so that the renumbering effect may be replicated. Subtree rename must
4980  * be supported, since renumbering a database will affect all its child
4981  * overlays.
4982  *
