Re: [apps-discuss] [pkix] PKIX text encodings

Simon,

The same kind of format is also used for keys:

https://datatracker.ietf.org/doc/rfc5915/
https://datatracker.ietf.org/doc/rfc5958/

Is it worth pointing to the media types for the objects?

If you're going to reference RFC 4648, then you need to specify which 
alphabet (the apps guys are always pointing this out).
