Saxon

From direct email:

I have a XQuery which modifies the content of /text/a and reserves CDATA in /test/pattern of a XML file.

xquery version "3.0";
declare namespace saxon = "http://saxon.sf.net/";
declare option saxon:output "cdata-section-elements=pattern";

let $doc := doc('testCDATA.xml')
return replace value of node $doc/test/a with 'fromxquery'

The XML file testCDATA.xml :

<test>
   <a>test</a>
  <pattern><![CDATA[(?<=(^|[^0-9]+))([0-9]+([-]+[0-9]+)*)(?=([^0-9]+|$))]]></pattern>
</test>

It works well in oXygen 19.1 with Saxon-EE 9.7.0.19

But if I run it with the Saxon (Saxon-EE 9.8.0.6J) command:

java -cp saxon9ee.jar net.sf.saxon.Query -t -backup:off -update:on -q:testCDATA.xquery

"CDATA" is get rid of the XML. It seems that options of serialization are not taken in Saxon for an update of the same file. If I missed something or it's a problem of Saxon?
