   * @param aXFormsNode     The XForms control upon which the expression
   *                        appears.  Used to allow our XForms XPath functions
   *                        access to the XForms document.
   * @param aContextNode    The original context node used to build and
   *                        evaluate the XPath expression.  This can be useful
   *                        to remember since this is the context node used
   *                        for the parse context part of XPath.  But the
   *                        context that our XFormsXPath functions has access
   *                        to is the evaluation context.  The context node
   *                        for the evaluation context can chnage as XPath
   *                        works its way through the expression.
