+ * Receive notification of basic DTD-related 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>If a SAX application needs information about notations and
+ * unparsed entities, then the application implements this
+ * interface and registers an instance with the SAX parser using
+ * the parser's setDTDHandler method. The parser uses the
+ * instance to report notation and unparsed entity declarations to
+ * the application.</p>
+ *
+ * <p>Note that this interface includes only those DTD events that
+ * the XML recommendation <em>requires</em> processors to report:
+ * notation and unparsed entity declarations.</p>
+ *
+ * <p>The SAX parser may report these events in any order, regardless
+ * of the order in which the notations and unparsed entities were
+ * declared; however, all DTD events must be reported after the
+ * document handler's startDocument event, and before the first
+ * startElement event.</p>
+ *
+ * <p>It is up to the application to store the information for
+ * future use (perhaps in a hash table or object tree).
+ * If the application encounters attributes of type "NOTATION",
+ * "ENTITY", or "ENTITIES", it can use the information that it
+ * obtained through this interface to find the entity and/or
+ * notation corresponding with the attribute value.</p>
+ *
