 * By implementing this interface, a collection can effectively say "other

 * The benefit of this, is that sabre/dav will by default perform a move, by
 * tranfersing an entire directory tree, copying every collection, and deleting
 * every item.
 *
 * If a backend supports a better optimized move operation, this can trigger
 * some huge speed gains.
