Specifically, the “Protection FEC Element TLV” uses the encoding and semantics of PWid FEC and Genercalize PWid FEC defined in RFC 4447. These FECs carry IPv4 addresses, and there is currently no IPv6 encoding defined for these FECs by IETF.

I have a hard time understanding how this document does not define a new 
encoding. The title of the section 6.4.1. is "Encoding Format for PWid" and 
the TLV type is 0x83 which is *not* defined in RFC4447. Can you please 
clarify what you mean? I think the proposal by Carlos to resolve this seems 
to be reasonable to me.

Thanks
Suresh
