7220  * should automatically renumber the index of any siblings as needed,
7221  * so that no gaps in the numbering sequence exist after the add/delete
7222  * is completed.
7223  *   What can be added:
7224  *     schema objects
7225  *     backend objects for backend-specific config directives
7226  *     database objects
7227  *     overlay objects
7228  *
7229  *   delete: probably no support this time around.
7230  *
7231  *   modrdn: generally not done. Will be invoked automatically by add/
7232  * delete to update numbering sequence. Perform as an explicit operation
7233  * so that the renumbering effect may be replicated. Subtree rename must
7234  * be supported, since renumbering a database will affect all its child
7235  * overlays.
7236  *
7237  *  modify: must be fully supported.
