Roughly, it denotes the set of elements X46 such that X46 is the sum of the members of the bag (like a set, but with possible duplicate elements) of elements X3 such that a certain set is not empty, namely the set of elements X48 such that X48 is the account number (JACCN) of a parcel whose number of p...
