7281  * should automatically renumber the index of any siblings as needed,
7282  * so that no gaps in the numbering sequence exist after the add/delete

7284  *   What can be added:
7285  *     schema objects
7286  *     backend objects for backend-specific config directives
7287  *     database objects
7288  *     overlay objects
7289  *
7290  *   delete: probably no support this time around.
7291  *
7292  *   modrdn: generally not done. Will be invoked automatically by add/
7293  * delete to update numbering sequence. Perform as an explicit operation
