6226  *   add / delete: all types that may be added or deleted must use an

6228  * should automatically renumber the index of any siblings as needed,
6229  * so that no gaps in the numbering sequence exist after the add/delete
6230  * is completed.
6231  *   What can be added:
6232  *     schema objects
6233  *     backend objects for backend-specific config directives
6234  *     database objects
6235  *     overlay objects
6236  *
6237  *   delete: probably no support this time around.
6238  *
6239  *   modrdn: generally not done. Will be invoked automatically by add/
6240  * delete to update numbering sequence. Perform as an explicit operation
6241  * so that the renumbering effect may be replicated. Subtree rename must
6242  * be supported, since renumbering a database will affect all its child
6243  * overlays.
