6936  *   add / delete: all types that may be added or deleted must use an

6938  * should automatically renumber the index of any siblings as needed,
6939  * so that no gaps in the numbering sequence exist after the add/delete
6940  * is completed.
6941  *   What can be added:
6942  *     schema objects
6943  *     backend objects for backend-specific config directives
6944  *     database objects
6945  *     overlay objects
6946  *
6947  *   delete: probably no support this time around.
6948  *
6949  *   modrdn: generally not done. Will be invoked automatically by add/
6950  * delete to update numbering sequence. Perform as an explicit operation
6951  * so that the renumbering effect may be replicated. Subtree rename must
6952  * be supported, since renumbering a database will affect all its child
6953  * overlays.
