count() returns wrong value

           Summary: count() returns wrong value
           Product: XalanJ2
           Version: CurrentCVS
          Platform: Other
        OS/Version: Other
            Status: NEW
          Severity: Critical
          Priority: Other
         Component: org.apache.xpath
        AssignedTo: xalan-dev@xml.apache.org
        ReportedBy: geuer-pollmann@nue.et-inf.uni-siegen.de


Given the code below, I create an attribute in an element and evaluate the 
XPath 

"count(ancestor-or-self::node())"

on that attribute. The ancestor-or-self axis should contain three nodes: The 
Attribute itself, it's owner element (which is also the document element) and 
the document node. But instead of 3.0, the evaluate call returns 4.0.

Regards,
Christian

DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
dbf.setNamespaceAware(true);
DocumentBuilder db = dbf.newDocumentBuilder();
Document doc = db.newDocument();
Element root = doc.createElement("root");
doc.appendChild(root);
Attr attr = doc.createAttribute("attr");
attr.setValue("val");
root.setAttributeNode(attr);

CachedXPathAPI xpathAPI = new CachedXPathAPI();
XObject includeInResult =
   xpathAPI.eval(attr, "count(ancestor-or-self::node())");
double val = includeInResult.num();

System.out.println("count(ancestor-of-self::node()) evaluates to " + val);
