 * {@link org.apache.jackrabbit.rmi.client.ClientItemDefinition ClientItemDefinition}
 * adapter base classes to provide transparent RMI access to remote item

 * Compex {@link javax.jcr.nodetype.NodeType NodeType} return values
 * are returned as remote references to the
 * {@link org.apache.jackrabbit.rmi.remote.RemoteNodeType RemoteNodeType}
 * interface. RMI errors are signalled with RemoteExceptions.
