     12  * The method getElementsByTagNameNS returns a NodeList of all the Elements with
     13  * a given local name and namespace URI in the order in which they are
     14  * encountered in a preorder traversal of the Document tree.
     15  *
     16  * Invoke the getElementsByTagNameNS method on a new Document object with the
     17  * values of namespaceURI=* and localName=*. This should return a nodeList of 1
     18  * item.
