equivalence relation on a set breaks it into disjoint sets. does 'disjointness' make sense in classes. specifically, given a category, isomorphism classes of objects makes sense or not. can it be so that initially we start with a class of objects,but equivalence classes form a set.

Can one talk about equivalences classes in a class(which might not be a set).
