// test 56: <form> and .elements
      var ok = false;
      test = document.getElementsByTagName('form')[0];
      if (// test.elements === test || // (IE would fail this, but HTML5 might require it)
          test.elements === test.getAttribute('elements') ||
          test.elements.length != 1 ||
          test.elements.length != test.elements)
        ok = false;
      if (ok)
        return 4;

The only part of that test that we fail is "form.elements.length == form.elements"

I'm not sure why that would be expected.  I guess HTMLCollection is supposed to have a special toNumber implementation which returns the number of elements in the collection!?

It would be nice to see a spec to back up that claim.

makes no such reference to this expected toNumber implementation.

See this is why you shouldn't look at the test before it's ready. :-P

It was supposed to test form.elements.length == form.length. Fixed the test. :-)
