    When it comes to using a cryptographic algorithm in DNSSEC there are two 
parts
    in the specification. The first is a general description of the
    cryptographic algorithm that applies to all contexts not just DNSSEC.
    The second is how the algorithm should be used in DNSSEC. Something about
    parameters and encoding of inputs and results.

    We can assume that cryptographic algorithms will be developed outside the 
    IETF and that by the time we make such an algorithm a SHOULD or RECOMMENDED 
a
    stable reference will be avaliable. So the thing the IETF needs to add is
    the second part. 

    So I think the requirement is obvious. If a cryptographic algorithm is to be
    listed as SHOULD or RECOMMENDED then a standard track specification of the
    second part is required.

    That means that if the code point was allocated based on a draft then a new
    draft that is intended for standards track needs to be created that copies 
the
    relevant material of the original draft. That provides a stable reference
    and gives room for review. It is very important to check that the new
    draft contains test vectors. Of course the new draft can immediately list
    the algorithm as SHOULD or RECOMMENDED.

    What I do not know, can a draft request IANA to update the reference for a
    previously allocated code point?

[ST] For 'bis' documents, we typically expect them to replace references to 
obsoleted documents, but the IANA Considerations section needs to tell us 
whether or not we should proceed with such updates. The IANA Considerations 
section can also tell us to replace references to any RFC or I-D, and we will 
do so once the IESG approves the document. If the existing reference points to 
a person rather than a document, we would check with that individual to confirm 
that they're OK with the change.

The IC section can also tell us to list it as an additional reference rather 
than replacing the existing one. However, if the obsoleted document serves as 
the current reference, it’s generally expected that the original reference 
would be replaced rather than add to it.

Hope this helps. If you have any other questions, you can also reach us at 
i...@iana.org.

Best regards,
Sabrina
