5906  *   add / delete: all types that may be added or deleted must use an

5908  * should automatically renumber the index of any siblings as needed,
5909  * so that no gaps in the numbering sequence exist after the add/delete
5910  * is completed.
5911  *   What can be added:
5912  *     schema objects
5913  *     backend objects for backend-specific config directives
5914  *     database objects
5915  *     overlay objects
5916  *
5917  *   delete: probably no support this time around.
5918  *
5919  *   modrdn: generally not done. Will be invoked automatically by add/
5920  * delete to update numbering sequence. Perform as an explicit operation
5921  * so that the renumbering effect may be replicated. Subtree rename must
5922  * be supported, since renumbering a database will affect all its child
