6935  *   add / delete: all types that may be added or deleted must use an

6937  * should automatically renumber the index of any siblings as needed,
6938  * so that no gaps in the numbering sequence exist after the add/delete
6939  * is completed.
6940  *   What can be added:
6941  *     schema objects
6942  *     backend objects for backend-specific config directives
6943  *     database objects
6944  *     overlay objects
6945  *
6946  *   delete: probably no support this time around.
6947  *
6948  *   modrdn: generally not done. Will be invoked automatically by add/
6949  * delete to update numbering sequence. Perform as an explicit operation
6950  * so that the renumbering effect may be replicated. Subtree rename must
6951  * be supported, since renumbering a database will affect all its child
6952  * overlays.
