Here is a boog:

  C:\Temp> type testxpath.xml
  <?xml version="1.0"?>
  <ns:doc xmlns:ns="some-ns-uri">
    <ns:node ns:attr="value"/>
  </ns:doc>

  C:\Temp> xmllint --shell testxpath.xml
  / > xpath //ns:node
  XPath error : Undefined namespace prefix
  xmlXPathEval: evaluation failed
  Object is empty (NULL)

Can it be that the xmlShell from debugXML.c doesn't register namespaces 
for the XPath evaluation context? Whatever it does or doesn't do, it is 
too late to track it now, I'm off to bed. We'll have a look at it on 
another day. :-)
