At the moment, just send patches.  The openssl_tpm2_engine is developed
on a groups.io mailing list:

https://groups.io/g/openssl-tpm2-engine/

You need an IETF specific tool (xml2rfc) to build the rfc from the xml,
but it's available in most distros as python3-xml2rfc.  If you don't
want to learn the IETF XML I can help you code up the patch to add that
to the draft spec.
