Just remember - IANA assigns numbers.   If you need a testing number before
IANA has done so, use a number less than -65536

Thanks, Jim.  We'll go with route number 3 then.

For myself, I do not believe that the IETF has any interest in the Brainpool
curves.   The different ways would be:

1.	Submit a document in the COSE WG - no something I would be
interested in
2.	Submit a document to the ISE - a reasonable way forward in my
opinion
3.	Just put the IANA registrations in to the ISO/ICE document and send
a request to IANA for registration - my preferred way forward.

Subject: [COSE] Registering Brainpool curves for COSE

The working group ISO/IEC JTC 001/SC 17 "Cards and security devices for
personal identification" Mobile Driver's License (mDL) specification uses
the Brainpool curves defined in RFC 5639, M. Lochter et. al., Elliptic Curve
Cryptography (ECC) Brainpool Standard Curves and Curve Generation, March
2010 with COSE..  Thus, it would like to have curve identifiers registered
for them.  Specifically, these curves and intended registration information
are:

brainpoolP256r1 RFC 5639 -65537 ECDH/ECDSA 

brainpoolP320r1 RFC 5639 -65538 ECDH/ECDSA 

brainpoolP384r1 RFC 5639 -65539 ECDH/ECDSA 

brainpoolP512r1 RFC 5639 -65540 ECDH/ECDSA

Is the best way to register these curves to create an Internet Draft and
submit it to the COSE working group or would you suggest another course to
accomplish this?

                                                                Thanks,
