Personally, I wouldn't use CallMethodRule here, but I rarely use it
anywhere. In this case, some options:
* Add a SetNextRule where you have access to both the "element" and
"subelement", and therefore, all params to call the method
* Add a custom rule that peeks one down the stack to find the
"element" (custom rules are not hard, ofcourse if you can do what you
need with "provided" rules, thats better most of the times)
