Re: [Pce] Martin Vigoureux's No Objection on draft-ietf-pce-lsp-control-request-09: (with COMMENT)

["Vigoureux, Martin (Nokia - FR/Paris-Saclay)" <[e-mail]>]

Thank you Deborah

I'm not entirely convinced. In my view the change is likely to have an 
impact on existing implementations (error handling part). From that 
point of view I feel Update wouldn't hurt in the sense that someone 
implementing 8231 might want to know that impact in advance. But we are 
down in the foggy subtleties of "Updates".
It might more be the case for an "Extends/Extended by".

Thank you for discussing my comment.
