docs: An alternative comparison function used by CollectionsType in conjunction with CompositeType.
  
  This comparator is only called to compare components of a CompositeType. It gets the value of the
  previous component as argument (or null if it's the first component of the composite).
  
  Unless you're doing something very similar to CollectionsType, you shouldn't override this.
