I find that the changes to version -23 prepared by Randall and provided in this archive mail are good: https://www.ietf.org/mail-archive/web/slim/current/msg01289.html That version allows answers to contain languages not contained in the offer (that was already allowed and well specified in version -23), and allows multiple languages per media and direction in the answer. I think both of these conditions are good and important for successful use of the draft. We need to imagine all kinds of feasible applications, e.g. the decision on including interpreting resources taken by the offeror after receiving the answer. That calls for providing the full and true picture about the supported languages in the answer. So, I repeat my comment from https://www.ietf.org/mail-archive/web/slim/current/msg01297.html "I find the diff you sent to be good, and also version -23 solving all other issues in a good way. So, I vote for applying your proposed changes on -23 and hope that that can be the final version."
