I updated this a bit and put it up <http://shadowregistry.org/js/misc/>.
I might try to add what other tests I have floating around. At least it
is very simple to add tests, just add something like

  // XPath root path always identifies root node
  var doc = new DOMParser().parseFromString("<y/>", "text/xml");
  var elm = doc.createElement("t");
  var re1 = doc.evaluate("/", doc, null, 9, null);
  var re2 = doc.evaluate("/", elm, null, 9, null);
  return re1.singleNodeValue === re2.singleNodeValue;

to a text file, no need to link specifications or encode author meta
data or writing description text or anything else. Adding comparative
data could be automized with some "submit data" button, which I haven't
done yet. Whether a test is correct is easy to tell by looking at the
comparative data and checking the code when in doubt, which is easy as
the tests are written with ease of review in mind.
