6547  *   add / delete: all types that may be added or deleted must use an

6549  * should automatically renumber the index of any siblings as needed,
6550  * so that no gaps in the numbering sequence exist after the add/delete
6551  * is completed.
6552  *   What can be added:
6553  *     schema objects
6554  *     backend objects for backend-specific config directives
6555  *     database objects
6556  *     overlay objects
6557  *
6558  *   delete: probably no support this time around.
6559  *
6560  *   modrdn: generally not done. Will be invoked automatically by add/
6561  * delete to update numbering sequence. Perform as an explicit operation
6562  * so that the renumbering effect may be replicated. Subtree rename must
6563  * be supported, since renumbering a database will affect all its child
