Notes
-----
o Update the Routing Backus-Naur Form (RBNF) [RFC5511] for Request
   message format: 

      * Update the request message to allows for the bundling of
      multiple path computation requests within a single Path
      Computation Request (PCReq) message.

      * Add <svec-list> in PCReq message. This object was  missed in
      [RFC6006].

      * Add BNC object in PCReq message. This object is required to
      support P2MP. It shares the same format as Include Route Object
      (IRO) but it is a different object. 
 
      * Update the <RRO-List> format to also allow Secondary Record
      Route object (SRRO). This object was  missed in [RFC6006].

      * Removed the BANDWIDTH Object followed by Record Route Object
      (RRO) from <RRO-List>. As BANDWIDTH object doesn't need to follow
      for each RRO in the <RRO-List>, there already exist BANDWIDTH
      object follow <RRO-List> and is backward compatible with
      [RFC5440].

      * Update the <end-point-rro-pair-list> to allow optional BANDWIDTH
      object only if <RRO-List> is included.
