The axiom https://github.com/ontologyportal/sumo/blob/master/Merge.kif#L452-L456 defines the semantics of range. The question is the necessity of the AssignmentFn. We don't have much information about this function. See here.

Maybe we can replace it with a more direct version:

(=> (and (range ?FUNCTION ?CLASS)
	 (equal (?FUNCTION @ROW) ?VALUE))
    (instance ?VALUE ?CLASS))
