Content Negotiation and validator

Recently I've been using Content Negotiation on one of my sites so 
browsers that don't understand application/xhtml+xml get served text/html

But I was wondering, how come the validator (http://validator.w3.org/) 
doesn't recognize  the correct MIME type?  When validating, it says it's 
text/html.  Shouldn't the validator be sending out headers just like any 
other user agent to say what MIME types it accepts?
