/**
 * This interface must be implemented by the ModelMBeans. An implementation of this interface
 * must be shipped with every JMX Agent.
 * <P>
 * Java resources wishing to be manageable instantiate the ModelMBean using the MBeanServer's
 * createMBean method.  The resource then sets the ModelMBeanInfo (with Descriptors) for the ModelMBean
 * instance. The attributes and operations exposed via the ModelMBeanInfo for the ModelMBean are accessible
 * from MBeans, connectors/adaptors like other MBeans. Through the ModelMBeanInfo Descriptors, values and methods in
 * the managed application can be defined and mapped to attributes and operations of the ModelMBean.
 * This mapping can be defined during development in an XML formatted file or dynamically and
 * programmatically at runtime.
 * <P>
 * Every ModelMBean which is instantiated in the MBeanServer becomes manageable:
 * its attributes and operations
 * become remotely accessible through the connectors/adaptors connected to that MBeanServer.
 * A Java object cannot be registered in the MBeanServer unless it is a JMX compliant MBean.
 * By instantiating a ModelMBean, resources are guaranteed that the MBean is valid.
 * <P>
 * MBeanException and RuntimeOperationsException must be thrown on every public method.  This allows
 * for wrapping exceptions from distributed communications (RMI, EJB, etc.).  These exceptions do
 * not have to be thrown by the implementation except in the scenarios described in the specification
 * and javadoc.
