officially, the w3 specifies that the way to access dom interfaces is through this class

so if you use

$doc = new DOMDocument("1.0", "UTF-8");

use instead:

$x = new DOMImplementation();
$doc = $x->createDocument(NULL,"rootElementName");
$doc->xmlVersion="1.0";
$doc->xmlEncoding="UTF-8";

it is not required by php's implementation, but, probably, it is a good practice
