But as I noted in my original review, your document does not say that. You
might argue that RFC 3692 says that (though it's not clear to me that it
precisely does), but as you don't cite it as a normative reference, you
can't rely on that either. If you'd like to modify the document to state
that (or point me to the text in your document which does so), I'll remove
my DISCUSS.
