6577  * should automatically renumber the index of any siblings as needed,
6578  * so that no gaps in the numbering sequence exist after the add/delete

6580  *   What can be added:
6581  *     schema objects
6582  *     backend objects for backend-specific config directives
6583  *     database objects
6584  *     overlay objects
6585  *
6586  *   delete: probably no support this time around.
6587  *
6588  *   modrdn: generally not done. Will be invoked automatically by add/
6589  * delete to update numbering sequence. Perform as an explicit operation
6590  * so that the renumbering effect may be replicated. Subtree rename must
