Build Identifier: 

XMLLists can contain non-xml. Take this code for example, where the indice of 0 is changed to a string:

    var x = new XMLList;
    x[0] = "alert(1)"
    uneval(x) == "alert(1)"
    // after bug 334628 is fixed: uneval(x) == "<>alert(1)</>"

Reproducible: Always

Steps to Reproduce:
1. Change an indice of an XMLList to a string.
2. uneval or use the toXMLString method.
Actual Results:  
"alert(1)"
After bug 334628 is fixed, it might be "<>alert(1)</>"

Expected Results:  
A TypeError is thrown.
Seems like a problem with E4X spec, invalid for Mozilla.
