     * new or removed entries are not touched in order not to modify the
     * transient status of the parent. Operations that affect the set or order
     * of child entries (AddNode, Move, Reorder) currently assert the
     * completeness of the ChildNodeEntries, therefore avoiding an update
     * resulting in inconsistent entries.
     *
     * @param childNodeInfos
     * @see HierarchyEntry#reload(boolean) that ignores items with
     * pending changes.
