          Partial Lock Remote Procedure Call (RPC) for NETCONF

Abstract

   The Network Configuration protocol (NETCONF) defines the lock and
   unlock Remote Procedure Calls (RPCs), used to lock entire
   configuration datastores.  In some situations, a way to lock only
   parts of a configuration datastore is required.  This document
   defines a capability-based extension to the NETCONF protocol for
   locking portions of a configuration datastore.
