/**
* SAX2 extension handler for DTD declaration events.
*
* <blockquote>
* <em>This module, both source code and documentation, is in the
* Public Domain, and comes with <strong>NO WARRANTY</strong>.</em>
* See <a href='http://www.saxproject.org'>http://www.saxproject.org</a>
* for further information.
* </blockquote>
*
* <p>This is an optional extension handler for SAX2 to provide more
* complete information about DTD declarations in an XML document.
* XML readers are not required to recognize this handler, and it
* is not part of core-only SAX2 distributions.</p>
*
* <p>Note that data-related DTD declarations (unparsed entities and
* notations) are already reported through the {@link
* org.xml.sax.DTDHandler DTDHandler} interface.</p>
*
* <p>If you are using the declaration handler together with a lexical
* handler, all of the events will occur between the
* {@link org.xml.sax.ext.LexicalHandler#startDTD startDTD} and the
* {@link org.xml.sax.ext.LexicalHandler#endDTD endDTD} events.</p>
*
* <p>To set the DeclHandler for an XML reader, use the
* {@link org.xml.sax.XMLReader#setProperty setProperty} method
* with the property name
* <code>http://xml.org/sax/properties/declaration-handler</code>
* and an object implementing this interface (or null) as the value.
* If the reader does not report declaration events, it will throw a
* {@link org.xml.sax.SAXNotRecognizedException SAXNotRecognizedException}
* when you attempt to register the handler.</p>
*
* @since SAX 2.0 (extensions 1.0)
* @author David Megginson
