/**
 * Remote version of the JCR {@link javax.jcr.Workspace Workspace} interface.
 * Used by the
 * {@link org.apache.jackrabbit.rmi.server.ServerWorkspace ServerWorkspace}
 * and
 * {@link org.apache.jackrabbit.rmi.client.ClientWorkspace ClientWorkspace}
 * adapters to provide transparent RMI access to remote workspaces.
 * 
 * Most of the methods in this interface are documented only with a reference
 * to a corresponding Workspace method. In these cases the remote object
 * will simply forward the method call to the underlying Workspace instance.
 * Complex return values like namespace registries and other objects are
 * returned as remote references to the corresponding remote interface. Simple
 * return values and possible exceptions are copied over the network
 * to the client. RMI errors are signaled with RemoteExceptions.
