with several examples. However, I was really trying to apply the same
consideration to feature registration that seems to be happening with
media type registration: shouldn't there be IETF features, vendor
features, private features, experimental features, in the same way?

It wasn't an issue of 'document reference' (I know that
standards-track documents can reference non-standards-track
documents).
