+/**
+ * Provides definitions of the attribute change notifications sent by MBeans.
+ * <P>
+ * It's up to the MBean owning the attribute of interest to create and send
+ * attribute change notifications when the attribute change occurs.
+ * So the <CODE>NotificationBroadcaster</CODE> interface has to be implemented
+ * by any MBean for which an attribute change is of interest.
+ * <P>
+ * Example:
+ * If an MBean called <CODE>myMbean</CODE> needs to notify registered listeners
+ * when its attribute:
+ * <BLOCKQUOTE><CODE>
+ *      String myString
+ * </CODE></BLOCKQUOTE>
+ * is modified, <CODE>myMbean</CODE> creates and emits the following notification:
+ * <BLOCKQUOTE><CODE>
+ * new AttributeChangeNotification(myMbean, sequenceNumber, timeStamp, msg,
+ *                                 "myString", "String", oldValue, newValue);
