I'm a little bit confused. By definition, a cell c is closed if there is no descendent of c that has the same measure of c.  How can we determine if they are descendants or not if we are not given the measures for each cell?

Ancestor/descendant is defined on dimensional attributes, i.e. it has nothing to do with measures.
