Hi all,

This was the email from my co-author I referenced during our IETF 122 session, 
regarding removing MQTT related text from the document, and adapting the title.

I was reminded the decision should be confirmed in the mailing list – so this 
is my official request for feedback/objections. I hope the chairs will watch 
this thread and evaluate consensus.

Thanks,
Francesca

Subject: [Ace] Updates to draft-ietf-ace-pubsub-profile
Dear Ace,
 Our discussions with Marco and Francesca led us to consider removing the 
remaining MQTT-related text from this document (which has been substantially 
reduced in revisions). Currently, the MQTT specifications are not at the same 
detail level as the CoAP. We also do not expect a client to support both MQTT 
and CoAP.

Following this, we suggest renaming the document to either
CoAP Publish-Subscribe Profile for Authentication and Authorization for 
Constrained Environments (ACE)

or

Key Management and End-to-End Message Protection for the Publish-Subscribe 
Architecture for the Constrained Application Protocol (CoAP) Using 
Authentication and Authorization for Constrained Environments (ACE)
(aligning with the names of the two related drafts:  
draft-ietf-ace-key-groupcomm-oscore:Key Management for Group Object Security 
for Constrained RESTful Environments (Group OSCORE) Using Authentication and 
Authorization for Constrained Environments (ACE) and
 draft-ietf-core-coap-pubsub:A publish-subscribe architecture for the 
Constrained Application Protocol (CoAP)).

Please let us know if you have any objections to removing MQTT. Could you also 
comment on renaming the draft?

Kind regards,
--Cigdem
