question about LDP restart...

[Zhi-Wei Lin <zwlin@lucent.com>]

Hi all,

I was just browsing some files, and came across two similar WG documents 
covering what I think are very similar areas:

draft-ietf-mpls-ldp-restart-00.txt (published Jan '02)
draft-ietf-mpls-ldp-ft-02.txt (published Oct '01)

My question is: since the ldp-ft already provides a solution, is 
referenced in GMPLS CR-LDP as the way to go, what was the reason for 
making the ldp-restart also a WG document?

Thanks for any clarification...
