  /**
   * AdaptiveResultTreeImpl is a adaptive DOM model for result tree fragments (RTF). It is
   * used in the case where the RTF is likely to be pure text yet it can still be a DOM tree.
   * It is designed for RTFs which have &lt;xsl:call-template&gt; or &lt;xsl:apply-templates&gt; in
   * the contents. Example:
   * <pre>
   *    &lt;xsl:variable name = "x"&gt;
   *      &lt;xsl:call-template name = "test"&gt;
   *         &lt;xsl:with-param name="a" select="."/&gt;
   *      &lt;/xsl:call-template&gt;
   *    &lt;/xsl:variable>
   * </pre>
   * <p>In this example the result produced by <xsl:call-template> is likely to be a single
   * Text node. But it can also be a DOM tree. This kind of RTF cannot be modelled by
   * SimpleResultTreeImpl.
   * <p>
   * AdaptiveResultTreeImpl can be considered as a smart switcher between SimpleResultTreeImpl
   * and SAXImpl. It treats the RTF as simple Text and uses the SimpleResultTreeImpl model
   * at the beginning. However, if it receives a call which indicates that this is a DOM tree
   * (e.g. startElement), it will automatically transform itself into a wrapper around a
   * SAXImpl. In this way we can have a light-weight model when the result only contains
   * simple text, while at the same time it still works when the RTF is a DOM tree.
   * <p>
   * All methods in this class are overridden to delegate the action to the wrapped SAXImpl object
   * if it is non-null, or delegate the action to the SimpleResultTreeImpl if there is no
   * wrapped SAXImpl.
   * <p>
   * %REVISIT% Can we combine this class with SimpleResultTreeImpl? I think it is possible, but
   * it will make SimpleResultTreeImpl more expensive. I will use two separate classes at
   * this time.
