Description:
------------
I was expecting importNode to preserve attribute namespaces.
It doesn't

Reproduce code:
---------------
<?php
// PHP 5.2.* namespace bug - importNode doesn't preserve attribute namespaces

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

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

$attr= $fromdom->firstChild->attributes->item(0);

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

// The following script gets round this bug

function importAttrNS($targetNode, $attr)
	{ // Last modified 2009-01-26	Imports an attribute without losing the NS, if present
	if ($attr->prefix=='') $targetNode->appendChild($targetNode->ownerDocument->importNode($attr));
	else $targetNode->setAttributeNS($attr->lookupNamespaceURI($attr->prefix), $attr->prefix.':'.$attr->name, $attr->value);
	}
?>

Expected result:
----------------
The imported attribute should keep its namespace.

Actual result:
--------------
The imported attribute becomes unnamespaced.
