* This interface must be implemented by the ModelMBeans. An implementation of this interface

* <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.
