               <p><strong>Important</strong>:  Each <a class="termref">node</a> in the subtree is consulted only once. If text has been collected from a descendant, but is referenced by another IDREF in some descendant node, then that second, or subsequent, reference is not followed. This is done to avoid infinite loops.  </p>
