Bpel-108-UsingXQuery $publisher - oracle.xml.parser.v2.XMLElement@8b8e58

Question

Hello,
I am using Oracle SOA Suite 11.1.1.4.0 While executing the XQuery example bpel-108-UsingXQuery I am facing the following problem/error.
The Xquery in the example is:
xquery version "1.0";
declare namespace ns0 = "http://example.com/bpel/books";
declare namespace ns1 = "http://samples.otn.com/xquerysample";
declare variable $category as node() external;
declare variable $publisher as xs:string external;
<bookReport>
for $b in //ns0:BOOKS/ns0:ITEM
where data($b/ns0:PUBLISHER) = $publisher
order by string-length($b/TITLE) return
<book>
<author> { data($b/ns0:AUTHOR) } </author>
<title> { data($b/ns0:TITLE) } </title>
<price>{ data(doc("pricelist.xml")/ns1:pricelist/ns1:product[1]/ns1:price) }</price>
<publisher>{ $publisher }</publisher>
{ $category }
</book>
</bookReport>
The variable $publisher, declared in 'declare variable $publisher as xs:string external' shall have the value 'Associated Press' as this has been assigned in the BPEL but it has in fact the value 'oracle.xml.parser.v2.XMLElement@8b8e58'.
The variable $category has the correct value.
What is here wrong or is it a bug in 11.1.1.4.0 in the oracle.xml.parser.v2.XMLElement class.

What a mess:
org.w3c.Element element = (org.w3c.Element) payload.get("payload");
private Document writeOraXMLtoDocument(org.w3c.Element payload) throws ParserConfigurationException, SAXException, IOException, TransformerException{
          ByteArrayInputStream inputStream = new ByteArrayInputStream(writeXMLToStream(new DOMSource(payload)).toByteArray());
          DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
          DocumentBuilder builder =factory.newDocumentBuilder();
          return builder.parse(inputStream);
     private ByteArrayOutputStream writeXMLToStream(Source source) throws TransformerException {
ByteArrayOutputStream out = new ByteArrayOutputStream();
// Prepare the output file
Result result = new StreamResult(out);
// Write the DOM document to the file
TransformerFactory x = TransformerFactory.newInstance();
Transformer xformer = x.newTransformer();
xformer.transform(source, result);
return out;
Note, that you have to use the oracle transformer located in the xmlparserv2.jar
if it is not your default transformer , you have to set it at least for the above code by System.setProperty("javax.xml.transform.TransformerFactory","..classname...");
