   This document specifies a CBOR encoding of X.509 certificates.  The
   resulting certificates are called C509 Certificates.  The CBOR
   encoding supports a large subset of RFC 5280 and significantly
   reduces the size of certificates compatible with e.g.  RFC 7925, IEEE
   802.1AR (DevID), CNSA, and CA/Browser Forum Baseline Requirements.
   When used to re-encode DER encoded X.509 certificates, the CBOR
   encoding can in many cases reduce the size of RFC 7925 profiled
   certificates with over 50%.  The CBOR encoded structure can
   alternatively be signed directly ("natively signed"), which does not
   require re-encoding for the signature to be verified.  The document
   also specifies COSE headers as well as a TLS certificate type for
   C509 certificates.

   NOTE: "C509" is a placeholder, name to be decided by the COSE WG.
