I have sample schema:

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema targetNamespace="http://www.test.com/app"
 xmlns:xs="http://www.w3.org/2001/XMLSchema"
 xmlns="http://www.test.com/app" elementFormDefault="qualified"
 version="1.0">
 <xs:element name="DocSample">
 <xs:complexType>
 <xs:sequence>
 <xs:element name="Element">
 </xs:element>
 </xs:sequence>
 </xs:complexType>
 </xs:element>
</xs:schema>

@XmlRootElement(name = "DocSample", namespace = "http://www.test.com/app")

}

Java code:

@Test
 public void testSample() {
 DocSample doc = new DocSample();
 doc.setElement(new String("sdsd"));

 StreamResult result = new StreamResult(new StringWriter());

 JAXBContext jaxbContext;
 try {
 jaxbContext = JAXBContext.newInstance(DocSample.class);
 Marshaller marshaller = jaxbContext.createMarshaller();
 marshaller.marshal(doc, result);

 } catch (JAXBException e) {

 e.printStackTrace();
 }

 String response = result.getWriter().toString();

 System.out.println(response);

 }

And result XML:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<DocSample xmlns="http://www.test.com/app">
 <Element xsi:type="xs:string"
 xmlns:xs="http://www.w3.org/2001/XMLSchema"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
 sdsd
 </Element>
</DocSample>

Is this XML correct? Why xmlns:xs, xmlns:xsi are assigned to Element, not DocSample. Please help.
