Hi all,

the IETF review has ended, so I have uploaded -03 version.

Magnus, Dan,

the -03 version addresses all your comments.

Tim,

I left the irtf documents in Normative as per Stephan's comments.

I believe that Section 8 correctly references IANA registry:
http://www.iana.org/assignments/dns-sec-alg-numbers/dns-sec-alg-numbers.xhtml
by its name.

The paragraph with nit has been removed altogether per Magnus's request.

Thank you all very much for the reviews.

Cheers,
--
