Document: draft-ietf-eppext-keyrelay-11
Reviewer: Robert Sparks
Review Date: 14Dec2015
IETF LC End Date: 4Dec2015
IESG Telechat date: 17Dec2015

Summary: (Still) ready for publication as Proposed Standard

Thanks for addressing most of my nits.

I think it's a problem (not for this document, but for the overall work) 
that draft-koch-dnsop-operator-change isn't moving forward. I think the 
group should spend energy on how to capture what it was saying.

I also still think you would have a stronger document if it discussed 
the SHOULD NOT in the security section as I suggest below. I think you 
read that to be me suggesting you change it to MUST NOT. That was not 
the intent. I was asking you to add to the document _why_ it wasn't MUST 
NOT.
