   * Instead, they always start from the root node. The node passed to
   * setStartNode() is not totally useless, though. It is needed to obtain the
   * DOM mask, i.e. the index into the MultiDOM table that corresponds to the
   * DOM "owning" the node.
   *
   * The DOM mask is cached, so successive calls to setStartNode() passing
   * nodes from other DOMs will have no effect (i.e. this iterator cannot
   * migrate between DOMs).
