Hi, 

I unfortunately didn't find the time to engage the group further about this document after my comments at the start of the year.

The ISO SC17/WG10 will run a test event in the middle of august for the current specification of the ISO 18013-5 draft
This draft integrates a COSE_Sign1 element using a x5chain header to reference a X509 certificate.
It would be very helpful if we could have a temporarily register value to use for that, instead of the TBD3 that's currently in table 1.
If it can't be done in time, we'll have to use some value reserved for private use, as per the COSE Header Parameters register, so below -65536, but it will be cool if we can do better.
Unfortunately we have very little time available, if we want to give sufficiently in advance the information to implementers about what they should use.

Best regards,
Jean-Marc

A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the CBOR Object Signing and Encryption WG of the IETF.

        Title           : CBOR Object Signing and Encryption (COSE): Headers for carrying and referencing X.509 certificates
        Author          : Jim Schaad
	Filename        : draft-ietf-cose-x509-02.txt
	Pages           : 10
	Date            : 2019-06-20

Abstract:
   The CBOR Signing And Encrypted Message (COSE) structure uses
   references to keys in general.  For some algorithms, additional
   properties are defined which carry parts of keys as needed.  The COSE
   Key structure is used for transporting keys outside of COSE messages.
   This document extends the way that keys can be identified and
   transported by providing attributes that refer to or contain X.509
   certificates.
