I would think of any certification as being part of the "communication
protocol". I could see a place in the data format for indicating the
source, description, and possibly a special field for the the source's
assessment of the quality. If you really want  certification ( =
authentication)  you should have the whole thing encrypted so that it
needs to be unencrypted with the source's public key, but you have to do
that outside the format description (and you need PKI infastructure to
do it correctly).
