OK

Here is my test file:

    </body>
</html>

The file is working, that is, I can change the content of the first
item element. I don't know why I need the b element and the binding.
This is a trick of mine to get the file working. Please inform me what
I can do instead.

*** Now, I have not succeeded in changing the z attribute value in the
second item element. That is why I have out commented it in the
JavaScript like this:
//itemElement1.setAttribute("z", "NEW ATT VALUE");

To get the update of the attribute working is my main problem. But it
would be nice if I could also be able to make new elements and
attributes.

I am going to use it all to make a shuffle routine in JavaScript that
can annotate the instance document with the proper randomized values
so the questions and their options get shuffled each time the user
take the test.
