  That's normal. Your elements are in a namespace, the default namespace
defined in the instance (xmlns="http://www.w3schools.com";) and in XPath
you must use a prefix in the query to access a namespaced node. The only
solution is to use /p:TU/p:Model and define a binding between p and
"http://www.w3schools.com"; in the XPath context. 

  This is really a very very frequently asked XPath question, the one that
each and every beginner to XPath who doesn't learn from a book or a tutorial
get hit with (assuming one uses namespaces)
