5951  *   add / delete: all types that may be added or deleted must use an

5953  * should automatically renumber the index of any siblings as needed,
5954  * so that no gaps in the numbering sequence exist after the add/delete
5955  * is completed.
5956  *   What can be added:
5957  *     schema objects
5958  *     backend objects for backend-specific config directives
5959  *     database objects
5960  *     overlay objects
5961  *
5962  *   delete: probably no support this time around.
5963  *
5964  *   modrdn: generally not done. Will be invoked automatically by add/
5965  * delete to update numbering sequence. Perform as an explicit operation
5966  * so that the renumbering effect may be replicated. Subtree rename must
5967  * be supported, since renumbering a database will affect all its child
5968  * overlays.
