Thanks for the suggestion. The point is now: does this format accept
any of the special encodings required for, say, strange AttributeTypes
that would be encoded with the OID, or UTF-8 values, or so? I still
need some sources :)

Sure, I don't think we need to go so far; Kurt already dropped
the UFN->DN transcoding.
