    If you will write a HTML document :

    // $xml = new XMLWriter();  you know it and openURI()

    <?php
    // for HTML 5
    $xml->startDTD('html');
    // for XHTML 1.0
    $xml->startDTD('html', '-//W3C//DTD XHTML 1.0 Strict//EN','http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd'); // standards compliant

    $xml->endDTD();
    ?>
    it will be :
    <!DOCTYPE html>
    or    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN">

    don't need to startDocument() .
