* "Unsolicited notification" is defined in
* <A HREF="ftp://ftp.isi.edu/in-notes/rfc2251.txt">RFC 2251</A>.
* It allows the server to send unsolicited notifications to the client.
* A <tt>UnsolicitedNotificationListener</tt> must:
*<ol>
* <li>Implement this interface and its method
* <li>Implement <tt>NamingListener.namingExceptionThrown()</tt> so
* that it will be notified of exceptions thrown while attempting to
* collect unsolicited notification events.
* <li>Register with the context using one of the <tt>addNamingListener()</tt>
* methods from <tt>EventContext</tt> or <tt>EventDirContext</tt>.
* Only the <tt>NamingListener</tt> argument of these methods are applicable;
* the rest are ignored for a <tt>UnsolicitedNotificationListener</tt>.
* (These arguments might be applicable to the listener if it implements
* other listener interfaces).
