I discussed this in my earlier mail and showed, in particular, that this
is no more or less robust than text/xml; the client still gets given a
label and still either knows what that label is or does not.

No, I am arguing specifically about the default for text/xml - the
registration can choose what that default is.

Agreed, but that was not what I said.

No, I was using autodetection in a different sense here, and it was
valuable of Tim Bray to point this out. What the XML spec refers to as
autodetection is not really autodetection. Its just reading a textual
label, the same as reading a MIME charset label.

Because text files should be transmissible as text; XML is a format for
marked up text.
