/**

 * Provides interfaces to SAX2 facilities that

 * conformant SAX drivers won't necessarily support.

 *

 * <p>

 * See <a target='_top' href='http://www.saxproject.org'>http://www.saxproject.org</a>

 * for more information about SAX.

 *

 * <p>

 * This package is independent of the SAX2 core, though the functionality

 * exposed generally needs to be implemented within a parser core.

 * That independence has several consequences:

 *

 * <ul>

 *

 * <li>SAX2 drivers are <em>not</em> required to recognize these handlers.

 * </li>

 *

 * <li>You cannot assume that the class files will be present in every SAX2

 * installation.</li>

 *

 * <li>This package may be updated independently of SAX2 (i.e. new

 * handlers and classes may be added without updating SAX2 itself).</li>

 *

 * <li>The new handlers are not implemented by the SAX2

 * <code>org.xml.sax.helpers.DefaultHandler</code> or

 * <code>org.xml.sax.helpers.XMLFilterImpl</code> classes.

 * You can subclass these if you need such behavior, or

 * use the helper classes found here.</li>

 *

 * <li>The handlers need to be registered differently than core SAX2

 * handlers.</li>

 *

 * </ul>

 *

 * <p>This package, SAX2-ext, is a standardized extension to SAX2.  It is

 * designed both to allow SAX parsers to pass certain types of information

 * to applications, and to serve as a simple model for other SAX2 parser

 * extension packages.  Not all such extension packages should need to

 * be recognized directly by parsers, however.

 * As an example, most validation systems can be cleanly layered on top

 * of parsers supporting the standardized SAX2 interfaces.

 *

 * @since 1.4
