    by default, the xmlns: definition is repeated on every element.
    if you do want the prefix, but dont want the xmlns: declaration repeated, set the namespace to null. dont forget to declare the namespace prefix somewhere higher in your document, though:
    <?php
    $w->startElementNS('foo', 'bar', 'http://example.com/foo');
    $w->startElementNS('foo', 'baz', null);
    $w->endElement();
    $w->endElement();
    ?>
    
    If you don't want any namespace prefix at all but still want the xmlns attribute, set $prefix to null.
