/**
* 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
