Yet it does seem to > adequately describe the problem and the way to deal with it. Since I'm opposed to "silence equals consent" mechanisms in general, I feel obligated to post a note about this. Although other possibilities would do equally well (and I have mixed feelings about the "syntax versus Security Considerations versus both" question), this change appears to me to be consistent with the conclusions reached last spring. I think it is more important to accept some reasonable change, such as this one, get the document published, and move on than to engage in a further lengthy debate about just which solution would be best in some abstract sense. I would _strongly_ suggest one small change, which is that the word "valid" replace "legal" whenever the latter occurs. We don't make laws around here. john
