Summary: Problem with taconite ajax

Initial Comment:
Hi all,
My webapp is using the taconite ajax implementation and
I run my tests under Canoo Web Test. 
Filling a combobox, with an ajax action, depends of the
value selected by the user from another combobox. 
The xml response received by the server for an ajax
call is the following :

<taconite-root>
<taconite-replace-children contextNodeID="country"
parseInBrowser="false">
<![CDATA[
var element0 = document.createDocumentFragment();
element0.appendChild(document.createTextNode("       "));

var element1 = document.createElement("option");
element1.setAttribute("value", "");
element0.appendChild(element1);
element0.appendChild(document.createTextNode("  "));
element0.appendChild(document.createTextNode("      "));

element1 = document.createElement("option");
element1.setAttribute("value", "30");
element0.appendChild(element1);
element1.appendChild(document.createTextNode("Brésil"));element0.appendChild(document.createTextNode("
     "));

and so on ...

The error is the following :

In fact this is the same problem as exposed in bug 1415496
[1]: the object returned by XMLHttpRequest.responseXML is
not a js host object for the JavaScript engine. The
consequence is that expressions like
XMLHttpRequest.responseXML.childNodes[0] fail with an
exception like the one you get.

Since the exception is not in english I can't tell for sure,
but it's probably because we have no support for
createDocumentFragment yet.
