Hi
i read this document over with fresh eyes and tried to ignore any history.
Summary: Publication considered harmful
Reasons: This document calls itself "Security Considerations" but in
reality all it is covering is "Publication considerations by Authority"
the document does not cover at all the consumption of RFC5011 events by
resolvers which IMHO are the more important part of the protocol.
