Hi Alissa,

Thank You for the review! Please see inline.

COMMENT:

> Since RFC 5245 is already obsolete, this document cannot obsolete it I don't think. 
> RFC 8445 references this document, so readers of that document will be able to find this one.

Ok, we will remove the "obsolete" part.

---

> Section 2: Please use the precise boilerplate from RFC 8174.

Will do.

---

> Section 4.1: It's not clear why IESG Approval is included as one of the registration policies to extend 
> the candidate attribute. Does the WG anticipate cases where IETF Review will not be appropriate? 
> And I agree with Alexey that a registry needs to be defined in the IANA Considerations section.

My suggestion (I think Alexey also gave it as an option) is to remove the text about the process for defining new name/value pairs, and only say that unsupported name/value pairs are discarded.

No one has ever brought an extension suggestion to IETF, AFAIK.

---

> Section 8: Agree with Ben about adding references to ICE and SDP security considerations.

Will do.

---

> Section 9.1.1: s/esg@ietf.org/iesg@ietf.org/

Will fix.

---

> Section 9.2: Further to Alexey's point, the minimal information necessary for the registry to function should be collected and/or published.

I suggest to only keep the following:

   o  The ICE option identifier to be registered

   o  Short description of the ICE extension to which the option relates

   o  Reference(s) to the specification defining the ICE option and the
      related extensions

---

Regards,

Christer
