Section 3 says:

   This document lists the implementation status of cryptographic
   algorithms used with DNSSEC.  These algorithms are maintained in an
   IANA registry at http://www.iana.org/assignments/dns-sec-alg-numbers.
   Because this document establishes the implementation status of every
   algorithm, it has been listed as a reference for the registry itself.

It should say:

   This document lists the implementation status of cryptographic
   algorithms used with DNSSEC.  These algorithms are maintained in an
   IANA registry at http://www.iana.org/assignments/dns-sec-alg-numbers.
   Because this document establishes the implementation status of every
   algorithm, it has been listed as a reference for the registry itself.

   Given significance of status change of RSAMD5 algorithm, a reference
   to this RFC should be added to the registry.

Notes:

"RSAMD5 has an implementation status of Must Not Implement because of known weaknesses in MD5."

This is very important. An additional reference would lower likelihood that DNS Implementors will overlook the important piece of information.
