XQuery on CDATA sections returns result as escaped XML text instead of original raw data.

Example code (see complete project attached) :

QXmlQuery xQuery;
xQuery.setQuery("doc('test.xml')/xml/string()");
QString result;
xQuery.evaluateTo(&result);
qDebug() << "Result = " << result;

With the following input test.xml file :

<xml>
<![CDATA[<tag>test</tag>]]>
</xml>

returns escaped output:
&lt;tag&gt;test&lt;/tag&gt;

instead of the correct output :
<tag>test</tag>

XQuery engine should leave the CDATA section untouched without any extra encoding because that's what CDATA sections are meant for.
