Incorrect code generation for predicate

           Summary: Incorrect code generation for predicate
           Product: XalanJ2
           Version: CurrentCVS
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: org.apache.xalan.xsltc
        AssignedTo: xalan-dev@xml.apache.org
        ReportedBy: zongaro@ca.ibm.com


Code generation for a predicate that involves a comparison of a step expression 
against a string value is incorrect in some circumstances.  Code in the 
isNodeValueTest(), getCompareValue() and getStep() methods of Predicate 
together detect an optimization opportunity that is too optimistic in some 
circumstances.

I'll attach an illustrative example - the general case needs to be carefully 
considered.
