A small question about the QNAME in the NOTIFY message. The draft says it
should be the server's host name, but that doesn't make sense to me: the
server already knows its name, but it doesn't know which domain's
delegation is to be updated. Should the QNAME be the latter?

Regarding timing and security considerations. The draft has some
discussion about timing requirements for the sender of the NOTIFY, but it
also envisages that anyone is able to send these NOTIFY requests. That
implies that if there are timing constraints they MUST be enforced by the
parent domain, otherwise attackers would be able to screw up a delegation
by forcing a change too soon. So I think a better approach to specifying
this functionality would be to minimise the requirements that are imposed
on the sender, and explain carefully the validity and timing checks that
the recipient must perform.
