I missed the cut-off date, but meanwhile it is available from:
The forms where part of earlier versions of draft-josefsson-dns-url, and there has been two versions of draft-josefsson-mime-dns published at IETF before, so the types may have been discussed here before; I don't recall. Still, this version has been improved in many ways, so I'd appreciate more review.
Looks basically OK to me. The one thing I noted that is missing is some discussion of the charset used for text/dns; I assume it is US-ASCII.
Ah, thanks, there should be some discussion about that. I think the document should acknowledge existing practice that comments can be encoded in some locally defined charset. (This is another interoperability issue, too.) As for non-comments, non-ASCII are probably in use, and to my reading they appear conforming to the specification. The non-ASCII octet values are not interpreted in any specific charset though, they are just treated as opaque binary octets. RFC 1035 (section 4) do allow for escape sequences like \DDD to express arbitrary octets, so the master files does not _have_ to be anything but ASCII, even if they represent arbitrary octets. I'm not sure how to phrase this in MIME terms though. Thoughts? It appears as if any valid MIME charset could be permitted, since the master file format only worries about that actual on-disk encoding, not the character interpretation. Thanks, Simon
