body: <p>Is there anyway to change the content-type of an XML document, in the XML document? </p>
  
  <p>I'm working with a really old system that passes back HTML (and we are trying to make it return XML).  I'm retrieving it from XMLHttpRequest, and I noticed using netcat that it isn't passing back any content-type headers.  </p>
  
  <p>When I receive the XMLHttpRequest.responseXML, the responseText exists but the responseXML is null.</p>
  
  <p>I've already checked the XML being returned to see if it is well formed and it appears to be (it's a very short document).</p>
