                           The current https://www.w3.org/TR/2015/REC-scxml-20150901/#finalize specification for
                           using an empty <finalize/> (no actions) is rather complex when:
                           - the invoke also has a namelist attribute and/or params with a location attribute
                           - and the event payload has values reachable by those namelist and/or params 'location' attributes
                           then the statemachine data at those locations should be updated with the payload values.

                           As the same functionality can be achieved (even if less convenient) by using a <finalize>
                           with <assign/> elements for each of these locations, *and* there are no SCXML IRP tests
                           for using an empty <finalize/>, the above logic is NOT implemented.
