There are two conflicting messages here, and I think it's critical that
this is addressed *quickly* :-). Otherwise a large number of servers will
have been set up where people guess the type (probably as text/xml), and
the chance of uniformity will have been missed. Personally I am neutral,
although given the effort that has gone into i18n, the thought of anything
tweaking the bits en route sounds horrid. The application has enough to do
without mending documents that have been tweaked for humans to read.

I would hope that there is only one MIME type for XML as it will be
impossible for most people to work out the difference. Two will simply
confuse people and they (the types) will simply serve as synonyms. From
what Rick says, application seems more logical, but I imagine there are
lots of text/sgml documents out there already and people will go by analogy.
