I tested a a few hours now, and didnt find any solution for this problem. When i
try to import a node from a different DOMDocument and append it to the current
DOMDocument, it fails without an error.

The same code snippet work in html files without any problems.
When i create the Node in the same Document, it works fine.

Reproducible: Always

Steps to Reproduce:
1. create a xul document with a box container specified by a id
2. run following javascript code snippet:
var xml = '<label>testlabel</label>';
var dom = (new DOMParser()).parseFromString(xml, "text/xml");
alert(dom.documentElement.nodeName);
    
var vbox = document.getElementById("content");
importedNode = document.importNode(dom.documentElement, true);
vbox.appendChild(dom.documentElement);

Actual Results:  
no results

Expected Results:  
add '<label>testlabel</label>' to the box. In the browser should displayed
"testlabel"

<label> needs to be in the XUL namespace if you want it to be a XUL element.
