title: DOMDocument::saveXML and LIBXML_NOEMPTYTAG option
body: <p>I'm facing the problem with the <code>DOMDocument</code>'s <code>saveXML()</code> function.</p>
  
  <p>When I call the <code>saveXML()</code> function on my Windows PHP 5.4.31 server, then the document is saved with expanded empty tags like when the <code>LIBXML_NOEMPTYTAG</code> is present (but it is not).</p>
  
  <p>What can I do when I do not want to expand the empty tags? Is there any default value I am missing, please?</p>
  
  <p>Thanks</p>
