request an OID for embedding CMWs in certs

[thomas-fossati]

Current work in TCG DICE and IETF "attested CSR" requires embedding CMWs in X.509 artefacts (certs and CSRs).

We should register the relevant OIDs with IANA.

Given cmw I-D more recently included cmw-collection, would it make sense for it to also define an ASN.1 form and register an OID?

My bad! I missed this definition from DICE-AA:

tcg-dice-conceptual-message-wrapper OBJECT IDENTIFIER ::= {tcg-dice 9}

I guess it can be used as-is?

OK, what's left is registering one OID for the collection, i.e.:

cmw-collection OBJECT IDENTIFIER ::= { TBD }

CMWCollection ::= OCTET STRING
