7263  *   add / delete: all types that may be added or deleted must use an

7265  * should automatically renumber the index of any siblings as needed,
7266  * so that no gaps in the numbering sequence exist after the add/delete
7267  * is completed.
7268  *   What can be added:
7269  *     schema objects
7270  *     backend objects for backend-specific config directives
7271  *     database objects
7272  *     overlay objects
7273  *
7274  *   delete: probably no support this time around.
7275  *
7276  *   modrdn: generally not done. Will be invoked automatically by add/
7277  * delete to update numbering sequence. Perform as an explicit operation
7278  * so that the renumbering effect may be replicated. Subtree rename must
7279  * be supported, since renumbering a database will affect all its child
