Section 2.3 discusses the issue of defining appropriate registration policy. I was wondering about consistency between the policies of similar registries, is it important and how to verify it. For example the policy for http://www.iana.org/assignments/sdp-security-descriptions/sdp-security-descriptions.xhtml#sdp-security-descriptions-3 is standard action and for http://www.iana.org/assignments/srtp-protection/srtp-protection.xhtml#srtp-protection-1 is specification required. I think that such cases should be discussed when defining the registration policy.
The policies do, indeed, need to be thought out when the documents are developed, and I think 5226bis is clear about that. But those decisions have to be made by those developing the documents, and I don't know what more we can say here about it, beyond what's here.
Do you have any specific suggestions?
