Hmm, I have been doing this via setAttributeNS(), with the XML namespace
namepace
define('NS_NS', 'http://www.w3.org/2000/xmlns/');
define('NS_XLINK', 'http://www.w3.org/1999/xlink');
$document = new DOMDocument();
$root = $document->createElement('root');
$document->appendChild($root);
$root->setAttributeNS(NS_NS, 'xmlns:xlink', NS_XLINK);
echo $document->saveXML();
Haven't encountered any problems with this method, seems to produce XML (SVG in
this case) fine.
