Dan, Simon, and I created yet another I-D for XML media types.
It is available at:
http://www.ietf.org/internet-drafts/draft-murata-xml-04.txt
The biggest change is the suffix. It is "+xml" rather than "|xml".
Miles Sabin pointed out that "|" is missing in some variations of
EBCDIC. We thus believe "|" is inappropriate. We believe that
the mojority of this ML prefer "+" to "-".
In reply to Rick Jelliffee, we added arguments against the charset
parameter of application/xml. We have also made it clear that users
are not forced to read and write %HH.
We are looking forward to your feedbacks.
