Ned Freed, main author of the MIME spec, has often commented that the 
_intent_ of the "text" MIME type was for information that could reasonable 
be displayed to a user as raw text.  He also comments that using 
"text/html" was probably a mistake, since displaying HTML as raw text is 
fairly unpopular with most users.

Therefore, it should probably _NOT_ be text/xml.  application/xml or 
application/soap+xml would be better.

The possibility of using message/soap+xml is an interesting option.  The 
difference between application/... and message/... is not always clear:  in 
terms of syntax, there is no real difference.  From past discussions with 
Ned, I understand that the intent of message/... types is to represent MIME 
objects whose content may be interpreted by a message handling element 
rather than handed off to an application.  It not always clear exactly what 
is the distinction.  I think the safe choice would be to use
