Not sure what your question is, but my understanding is that you are confused about the entries related to namespace, right?
There are two namespaces used in this bit of XML. One is 'xsd' which is the standard XML Schema namespace. The second is your personal namespace, which BTW is also the default namesapce. It is called the default namespace because you did not give a prefix to that namespace when you declared it.
Hope that help. If there are other questions please let us know.
