If so: which problem do you have with 9d289715eb5c2 or = draft-ietf-6man-deprecate-atomfrag-generation-06? Thank you for your reply. I was wrong. That real problem may not be 9d289715eb5c2, Because Roy said "TAHI should be updated". But I don't understand that real problem is in Test Tool or draft-ietf-= 6man-deprecate-atomfrag-generation-06. I am conforming it. Regards, Yuki Machida > > Hagen >
