Martin,

  I have pushed a -07 version of the document which I believe addresses the requested changes.

I believe that fully captures Zahed's review, yes.

Ran,

  I’m always open to adding explanatory material here – and it’s good to get feedback on what things require that kind of clarification.

Martin,

  I am, personally, not opposed to a registry. As you said, it is a little bit of text.  Happy to add it based on your thoughts regarding future interop.

  I will update the -06 draft as discussed so far in this thread.  I think the upcoming -07 would resolve AD comments so far. Is that correct?

-Ed

OK, so there's a slight revision of (6.1), possibly Ran's other editorial comments, and we have to resolve this registry issue.

IMO interoperability problems are an issue for whomever writes the extension, not for you. For a flag that changes the format, this would have to be negotiated. For something that doesn't, it might just provide additional information or trigger some other behavior that doesn't break the whole decrypt operation. I am not going to lie down in the road on this registry issue (though Zahed might?) but it's a pretty small bit of text and one decision on what RFC 8126 policy to use.
