Summary:  Not Ready


Major Concerns: 


The Security Considerations include this paragraph:

   Signed Marks are used primarily for sunrise domain name registrations
   in gTLDs, but other third-parties might be using them.  A party using
   Signed Marks should verify that the digital signature is valid based
   on local policy.  In the case of gTLDs, the RPM Requirements document
   [ICANN-TMCH] defines such policy.

The RPM Requirements document [ICANN-TMCH] does not seem to say anything
at all about validating a digital signature.

Protocols that make use of certificates perform some checks on the
certificate subject name to ensure that it represents an appropriate
signer.  That is missing from this document, and it is not contained in
[ICANN-TMCH] either.


Minor Concerns:

Section 2, second paragraph, I think that use of the phrase "in the
appropriate objects" ass ambiguity.  I suggest:

   This section defines some elements as OPTIONAL.  If an elements is
   not defined as OPTIONAL, then it MUST be included in the object.

The NOTE at the end of Section 2.3 about choosing an algorithm other
that RSA-SHA256 is better suited for the Security Considerations.
It would be helpful to say something more about the needed security
strength.

Why is RFC5730 a normative reference?  I do not see a dependency.
