No, sorry. Any single server is set up the way it is set up.
But I thought that what you suggested was that we use the
server settings to decide how to type file uploads. While
this is okay for actual uploads to a server (because there
is no specific protocol for such uploads, and we just have
to assume external knowledge), I don't think it's okay
for uploads to the validator, which come from any arbitrary
third party which may use extensions rather different from
those used at W3C.

No, there is a difference between server setup based on extensions
and sniffing of unrelated third-party files.

I agree that text/*+xml doesn't have that many uses. But it does
not contradict the XML specification. For details, please see

Again, if, as it seems, mime types on file upload isn't reliable,
I have no problem ignoring them. But pretending that the file is
served from our server doesn't look like a solution to me.
(The file is never actually served from our server, not ever
