PHP: Using DOM classes to build <script> elements

I have an HTML generator that uses the DOM classes to build documents and produce HTML. My target is HTML-compatible XHTML as outlined in Appendix C of the XHTML 1.0 spec.

This is a problem producing <script> elements: 

$document = new \DOMDocument();
$element = $document->createElement('script');
$script = $document->createTextNode('console.log(1 && 1);');
$element->appendChild($script);
$document->appendChild($element);
echo $document->saveXML($document->childNodes[0]);

Actual output:

<script>console.log(1 &amp;&amp; 1);</script>

Desired output:

<script>console.log(1 && 1);</script>

How do I get the desired output with the entities not escaped?

The correct answer must account for the fact that this situation occurs in a generator that generates all sorts of HTML elements, not just <script>, and generates proper XHTML. (That's why I use saveXML instead of saveHTML in the first place.) If an answer causes the generator to fail or misproduce other HTML elements, it isn't the correct answer.

Don't saveXML, use saveHTML.

$document = new \DOMDocument();
$element = $document->createElement('script');
$script = $document->createTextNode('console.log(1 && 1);');
$element->appendChild($script);
$document->appendChild($element);
echo $document->saveHTML($document->childNodes[0]);

In XML an & is marking an entity.
