Thanks, the proposed text is fine! Agree it is a minor item.

Thank you for this Esko. Hmm, point taken.

I consider this a minor change and we will incorporate it in the AUTH48 phase. 
I am planning to rephrase to
   "[...] If the client had requested Content-
   Format TBD287 (application/pkix-cert), the
   server would respond with a single DER binary certificate.
   That certificate would be in a multipart-core container specifically
   in the case of a response to /est/skc query."

Let us know if you have any objections.

Rgs,
Panos

Hello Panos,

I noticed one sentence in Appendix A that seems inconsistent with the rest of 
the I-D, or at least gives an incomplete view :

   If the client had requested Content-
   Format TBD287 (application/pkix-cert) by querying /est/skc, the
   server would respond with a single DER binary certificate in the
   multipart-core container.

The client here could also have POSTed to resource /est/sen with Accept:TBD287 
option, indicating it is requesting TBD287 for simple enrollment, and the 
server would respond with a single DER binary certificate 
(application/pkix-cert). So the current text might suggest that POSTing to 
/est/skc is the only way to request TBD287 format, which is not the case since 
/est/sen also may support it too.

Best regards
Esko

A New Internet-Draft is available from the on-line Internet-Drafts 
directories.
This draft is a work item of the Authentication and Authorization for 
Constrained Environments WG of the IETF.

        Title           : EST over secure CoAP (EST-coaps)

Abstract:
   Enrollment over Secure Transport (EST) is used as a certificate
   provisioning protocol over HTTPS.  Low-resource devices often use the
   lightweight Constrained Application Protocol (CoAP) for message
   exchanges.  This document defines how to transport EST payloads over
   secure CoAP (EST-coaps), which allows constrained devices to use
   existing EST functionality for provisioning certificates.
