  /**
   * <code>LSSerializerFilter</code>s provide applications the ability to
   * examine nodes as they are being serialized and decide what nodes should
   * be serialized or not. The <code>LSSerializerFilter</code> interface is
   * based on the <code>NodeFilter</code> interface defined in [<a href='http://www.w3.org/TR/2000/REC-DOM-Level-2-Traversal-Range-20001113'>DOM Level 2 Traversal and      Range</a>]
   * .
   * <p> <code>Document</code>, <code>DocumentType</code>,
   * <code>DocumentFragment</code>, <code>Notation</code>, <code>Entity</code>
   * , and children of <code>Attr</code> nodes are not passed to the filter.
   * The child nodes of an <code>EntityReference</code> node are only passed
   * to the filter if the <code>EntityReference</code> node is skipped by the
   * method <code>LSParserFilter.acceptNode()</code>.
   * <p> When serializing an <code>Element</code>, the element is passed to the
   * filter before any of its attributes are passed to the filter. Namespace
   * declaration attributes, and default attributes (except in the case when "
   * discard-default-content" is set to <code>false</code>), are never passed
   * to the filter.
   * <p> The result of any attempt to modify a node passed to a
   * <code>LSSerializerFilter</code> is implementation dependent.
   * <p> DOM applications must not raise exceptions in a filter. The effect of
   * throwing exceptions from a filter is DOM implementation dependent.
   * <p> For efficiency, a node passed to the filter may not be the same as the
   * one that is actually in the tree. And the actual node (node object
   * identity) may be reused during the process of filtering and serializing a
   * document.
   * <p>See also the <a href='http://www.w3.org/TR/2004/REC-DOM-Level-3-LS-20040407'>Document Object Model (DOM) Level 3 Load
   * and Save Specification</a>.
