http://xhr.spec.whatwg.org/#dom-xmlhttprequest is the specification.
It defines that XHR's document is set to the document associated with
the global object of XHR's interface object when the constructor is
invoked. A piece of code was given by bz:

window.onload = function() {
  document.open()
  var x = new XMLHttpRequest; // what document?
}

This document is later used by the open() method of XHR, which also
checks it's fully active and throws an exception otherwise.
