Danny, I understand your point. Yes the MAC extension field in 6.1.4.3 has 
to be described more clearly. But why should we need a special draft for a 
MAC extension field. There is already the draft 
"draft-ietf-ntp-extension-field" which should me general enough for 
additional new extension fields.
