Re: Discusses on GIST (draft-ietf-nsis-ntlp) regarding query message interception

Just to be clear, I am *not* asking you to change the document back to  
RAO. I have cleared my discuss regardless of it stays with the current  
intercept scheme or moves back to RAO. I actually missed the part  
where the IESG came to the conclusion that is needed to be changed  
back to RAO but if that's what the AD wants, I'm ok with that..
