I believe the Security Considerations section needs a small addition
to avoid being too vague. It currently just says "Therefore, as usual
adequate security measures are RECOMMENDED ..." without giving any
hint as to what those measures are or where to find any. Admittedly,
this draft is an update to RFC 5760 and a reasonable non-exclusive
list of such measures occurs in that RFC. Nevertheless, I would be
