/**
 * Remote version of the JCR {@link javax.jcr.nodetype.ItemDefinition ItemDef}
 * interface. Used by the
 * {@link org.apache.jackrabbit.rmi.server.ServerItemDefinition ServerItemDefinition} and
 * {@link org.apache.jackrabbit.rmi.client.ClientItemDefinition ClientItemDefinition}
 * adapter base classes to provide transparent RMI access to remote item
 * definitions.
 * 
 * The methods in this interface are documented only with a reference
 * to a corresponding ItemDef method. The remote object will simply forward
 * the method call to the underlying ItemDef instance. Argument and return
 * values, as well as possible exceptions, are copied over the network.
 * Complex {@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 signaled with RemoteExceptions.
