Xpath support in Xalan does not work if default namespace is used
-----------------------------------------------------------------

                 Key: XALANJ-2469
                 URL: https://issues.apache.org/jira/browse/XALANJ-2469
             Project: XalanJ2
          Issue Type: Bug
      Security Level: No security risk; visible to anyone (Ordinary problems in Xalan projects.
 Anybody can view the issue.)
          Components: XPath
    Affects Versions: 2.0.x
         Environment: Windows, IBM WebSphere Application Server - ND,  	6.1.0.7
            Reporter: rohit singh
            Priority: Blocker
             Fix For: 2.0.x


We are trying to use path for example "/Invoice/InvoiceHeader/InvoiceParty" as an X-Path expression.
The XML document on which this xpath is evaluated has a default namespace defined. This xpath
expression does return the specified elements value. I check the specification on xpath 1.0
on this url http://www.w3.org/TR/xpath and got this text below 

"There is an element node for every element in the document. An element node has an expanded-name
computed by expanding the QName of the element specified in the tag in accordance with the
XML Namespaces Recommendation [XML Names]. The namespace URI of the element's expanded-name
will be null if the QName has no prefix and there is no applicable default namespace."

According to the above the xpath should work irrespective of whether we have specified a default
namespace or not. Please take this as a high priority and fix this problem.
