/**
 * @deprecated RMI support is deprecated and will be removed in a future version of Jackrabbit; see Jira ticket JCR-4972 for more information.
 * 
 * Remote version of the JCR {@link javax.jcr.Item Item} interface.
 * Used by the  {@link org.apache.jackrabbit.rmi.server.ServerItem ServerItem}
 * and {@link org.apache.jackrabbit.rmi.client.ClientItem ClientItem}
 * adapter base classes to provide transparent RMI access to remote items.
 * 
 * The methods in this interface are documented only with a reference
 * to a corresponding Item method. The remote object will simply forward
 * the method call to the underlying Item instance. Argument and return
 * values, as well as possible exceptions, are copied over the network.
 * Complex return values (Items and Nodes) are returned as remote references
 * to the corresponding remote interfaces. RMI errors are signaled with
 * RemoteExceptions.
 *
