It appears that something is wrong with the commits. Could it be that your changes were committed --amend to the latest merge commit?

I've taken the liberty to force-push a version that has an actual commit in there.

I have now tested this and it works on self-interop. Let's see if we can even squeeze one more interop test into this hackathon.

I believe all is addressed.

We're not there yet: from interop, we did {/kccs/14: <<{...}>>} while Marco (and the IANA registry) say it is {/kccs/14: {...}}

Final part of the fix provided in PR #281.
