Hi,

I would like to ask if VIA parameter is mandatory or not. Currently the
draft seems not clear on this, the first paragraph tells that responder
may include addresses, while second tells it must do so

After the responder receives a relayed I1 packet, it can begin to
   send HIP packets addressed to the initiator's IP address, without
   further assistance from an RVS.  For debugging purposes, it MAY
   include a subset of the IP addresses of its RVSs in some of these
   packets.  When a responder does so, it MUST append a newly created
   VIA_RVS parameter at the end of the HIP packet. 

When a responder replies to an I1 relayed via an RVS, it MUST append
   to the regular R1 header a VIA_RVS parameter containing the IP
   addresses of the traversed RVS's.
