Which style am I using?

[Dimitris Mouchritsas]

Hi everyone,
I'm kind of new in web services so I need your help once again.
Say I have the following wsdl:
....
....
<wsdl:definitions targetNamespace="http://www.example.org";>
    <wsdl:documentation>
            Blah blah
</wsdl:documentation>
    <wsdl:types>
      <xs:schema targetNamespace="http://www.example.org";
attributeFormDefault="qualified" elementFormDefault="qualified">
        <xs:element name="viewLesson">
          <xs:complexType>
            <xs:sequence>
              <xs:element name="lesson_id" type="xs:long"/>
            </xs:sequence>
          </xs:complexType>
       </xs:element>
     </xs:schema>
  </wsdl:types>
  <wsdl:message name="viewLessonMessage">
    <wsdl:part name="part1" element="ns0:viewObservation"/>
  </wsdl:message>
    <wsdl:message name="viewLessonResponse">
   <wsdl:part name="part1" element="ns0:viewLessonResponse"/>
</wsdl:message>
....
....
so I send and receive messages like (minus the soap envelope):
<ns0:viewLesson  ...namespace stuff....>
  <ns0:lesson_id>1</ns0:lesson_id>
</ns0:viewLesson>

Which style am I using? I think I'm using document/wrapped but am I right?
I've read the
developer works article on this but I'm not certain yet.  Thanks in advance.
