Hi,
Because of time limited, I also post the comments here:
1. It would be better to align the same protection concept with 
draft-ietf-mpls-seamless-mpls. In draft-seamless, it uses BGP anycast 
protection, and the context ID is the anycast address. The key point of 
protection method in draft-seamless and your draft are the same, by using 
anycast address. Maybe we can change the name to PW anycast protection...
2. Need more description of BGP procedure in this draft. The BGP procedure 
on protection PE is special for such kind fast protection.

Thanks
Lizhong
