Description:
------------
I was expecting importNode to respect namespace

Reproduce code:
---------------
<?php
// PHP 5.2.* namespace bug - importNode doesn't preserve the namespace if deep=0. 

$aDOM= new DOMDocument();
$aDOM->appendChild($aDOM->createElementNS(' http://friend2friend.net/ ','f2f:a'));
echo 'DOM to add into is '.$aDOM->saveXML().chr(13);

$fromdom= DOMDocument::loadXML('<data xmlns=" http://altruists.org "/>');
echo 'Dom to import from is'.$fromdom->saveXML().chr(13);

$data= $fromdom->firstChild;

$aDOM->documentElement->appendChild($aDOM->importNode($data));
echo 'Result is '.$aDOM->saveXML();

?>

Expected result:
----------------
The manual says "This function returns a copy of the node to import and associates it with the current document. " so I was expecting it to preserve the namespace

Actual result:
--------------
The namespace gets lost.
