<MB>I have a hard time thinking to replace an RFC reference to a draft in a document that would become an Internet Standard. Moreover, I think the reference is more about “please look at ways to cache data” more than a hard requirement. So I disagree with your proposal. The new -05 do not contain any change in that regard. So I’m looking for your reply if you still want me to change the reference</MB>

<MB>At the time of writing the first draft, I took what was used in other RFCs for a  formal JSON definition. I agree that CDDL seems nicer and easier to understand and follow. However, I’m kinda not too warm about changing a formal specification while there are no changes in fact on the specification, for pushing the document in Internet Standard.  People reading the diff will think that the specification has changed, while it has not. The new -05 do not contain any change in that regard. So I’m looking for your reply if you still want me to use this CDDL snippet</MB>
