Re: [Roll] AD Review of draft-ietf-roll-turnon-rfc8138-07

Works for me, Alvaro. 

Please note that we must do the same change in useofrplinfo for the 0x23 enable flag.
The result is visible in github at https://github.com/roll-wg/roll-turnon-rfc8138 
I cannot publish during the cutoff but I'll do it first thing next week?

Please let me know if there's anything else.

May, many thanks Alvaro!

Pascal
