And other specs say other things. The document can be more than one 
thing at once. If it's well-formed, it is XML. Maybe it's HTML too, 
though I do think you're confusing what it's processed as with what it is.

Furthermore I disagree that that the MIME type describes how a document 
is processed. This is provably false. I routinely process documents as 
other than their MIME type says.

The MIME type is a hint the server provides saying how it sees this 
document. The client is free to follow that hint or not. Different 
clients can and will choose different processing that suits their needs. 
  The server does not know and cannot control what the client does.
