Saxon

When executing the below code I obtain this exception:

Exception in thread "main" java.lang.IllegalArgumentException: Value of {cdata-section-elements} must be a list of QNames in '{uri}local' notation
	at net.sf.saxon.s9api.Serializer.setOutputProperty(Serializer.java:490)
	at net.sf.saxon.jaxp.TransformerImpl.transform(TransformerImpl.java:142)
	at com.oxygenxml.transformer.XSLOutputException.main(XSLOutputException.java:44)

    Source xslSource = new StreamSource(new StringReader("<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n" + 
        "<xsl:stylesheet xmlns:xsl=\"http://www.w3.org/1999/XSL/Transform\"\n" + 
        "   version=\"1.0\">\n" + 
        "   \n" + 
        "   <xsl:output cdata-section-elements=\"MASTER_COMMENTS\"/>\n" + 
        "   \n" + 
        "   <xsl:template match=\"@* | node()\">\n" + 
        "      <xsl:copy>\n" + 
        "         <xsl:apply-templates select=\"@* | node()\"/>\n" + 
        "      </xsl:copy>\n" + 
        "   </xsl:template>\n" + 
        "</xsl:stylesheet>"));
    
    Transformer newTransformer = TransformerFactoryImpl.newInstance().newTransformer(xslSource);
    String outputProperty = newTransformer.getOutputProperty("cdata-section-elements");
    System.out.println("cdata-section-elements " + outputProperty);
    
    Source xmlSource = new StreamSource(new StringReader("<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n" + 
        "<MASTER_COMMENTS>\n" + 

    "</MASTER_COMMENTS>"));

StringWriter writer = new StringWriter();

Result outputTarget = new StreamResult(writer);

newTransformer.transform(xmlSource, outputTarget);


System.out.println(writer.toString());

The strange part is that the exception is triggered by the presence of this line of code:

String outputProperty = newTransformer.getOutputProperty("cdata-section-elements");

As far as I can tell, net.sf.saxon.lib.SaxonOutputKeys.parseListOfNodeNames(String, NamespaceResolver, boolean, boolean, String) builds clark notations like {}MASTER_COMMENTS and a bit later SaxonOutputKeys.checkListOfClarkNames considers them invalid.
