+/**
+ * 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>
+ * </blockquote>
+ *
+ * <p>This is an optional extension handler for SAX2 to provide
+ * information about DTD declarations in an XML document. XML
+ * readers are not required to support this handler.</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 propertyId "http://xml.org/sax/handlers/DeclHandler".
+ * If the reader does not support declaration events, it will throw a
+ * {@link org.xml.sax.SAXNotRecognizedException SAXNotRecognizedException}
+ * or a
+ * {@link org.xml.sax.SAXNotSupportedException SAXNotSupportedException}
+ * when you attempt to register the handler.</p>
