4999  *   add / delete: all types that may be added or deleted must use an

5001  * should automatically renumber the index of any siblings as needed,
5002  * so that no gaps in the numbering sequence exist after the add/delete
5003  * is completed.
5004  *   What can be added:
5005  *     schema objects
5006  *     backend objects for backend-specific config directives
5007  *     database objects
5008  *     overlay objects
5009  *
5010  *   delete: probably no support this time around.
5011  *
5012  *   modrdn: generally not done. Will be invoked automatically by add/
5013  * delete to update numbering sequence. Perform as an explicit operation
5014  * so that the renumbering effect may be replicated. Subtree rename must
5015  * be supported, since renumbering a database will affect all its child
