// Why all values in the last case: imagine that mapping M evaluated to "minus: A" on delta D.
// The mapping itself is in minus set, so it disappears when delta D is applied. Therefore, value of A
// was originally produced by the mapping M, and the mapping was originally active. So originally there was value of A
// present, and we have to remove it. See MID-3325 / TestNullAttribute story.
//
// The same argument is valid for zero set of mapping output.
//
// Finally, the plus set of mapping output goes to resulting minus just for historical reasons... it was implemented
// in this way for a long time. It seems to be unnecessary but also harmless. So let's keep it there, for now.
