6884  * should automatically renumber the index of any siblings as needed,
6885  * so that no gaps in the numbering sequence exist after the add/delete
6886  * is completed.
6887  *   What can be added:
6888  *     schema objects
6889  *     backend objects for backend-specific config directives
6890  *     database objects
6891  *     overlay objects
6892  *
6893  *   delete: probably no support this time around.
6894  *
6895  *   modrdn: generally not done. Will be invoked automatically by add/
6896  * delete to update numbering sequence. Perform as an explicit operation
6897  * so that the renumbering effect may be replicated. Subtree rename must
6898  * be supported, since renumbering a database will affect all its child
6899  * overlays.
6900  *
6901  *  modify: must be fully supported.
