Alan,

 

This approach seems fine.  Please add an RFC reference for the STUN rules, preferably citing a section # to make the rules easy to find (if you had trouble locating them, it’ll be even harder for other readers ...).

 

Thanks,
--David

Hi Jari,

 

We unfortunately did not reply to David for his review - our mistake.  See below for our response.

Thanks for your review, David. I am trying to determine
how to deal with this draft in the upcoming IESG telechat.
Has there been any discussion of the issue you raise?
Do the authors have a response?

David,

 

Apologies for not responding to you earlier earlier.  Since this text was written, we have realized that there are no valid use cases for HTTP, SIP, or XMPP for multiple Origins, and also that the STUN specification says that even if multiples were sent, only the first will be processed.  So we are dropping the MUST that you reference here.  We also plan to change the multiple Origins language in section 2 to say:  

 

"Senders SHOULD NOT include multiple ORIGIN attributes in a request since per STUN rules, only the first will be processed and the rest ignored."

RFC 7350 is DTLS transport for STUN, so we should reference it in the Security Considerations when we discuss DTLS.
