unexpected behaviour of XalanDOMString::erase(index, num) with default values

           Summary: unexpected behaviour of XalanDOMString::erase(index,
                    num) with default values
           Product: XalanC
           Version: 1.6
          Platform: Other
        OS/Version: Other
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: XalanC
        AssignedTo: [EMAIL PROTECTED]
        ReportedBy: [EMAIL PROTECTED]


basic_string &erase( size_type index = 0, size_type num = npos );
The parameters index and num have default values, which means that erase() can 
be called with just index to erase all characters after index.

if the num parameter is omitted, XalanDOMString::erase(index) behaves as if 
called with XalanDOMString::erase(index, length()), like stl string i think the 
expected behaviour is XalanDOMString::erase(index, length()-index) instead.
