I like MK's proposal, because I like one side effect that should not be adopted
without reailzing it:  The "datatypes that participate in the definition"
presumably are those that go into the (possibly ancestor) union definition may
have all their values removed from the union data space, but presumably these
datatypes remain member types of the restricted union under this definition. 
OTOH, if all of such a datatype's values have been removed by subsequent
restriction, they surely "no longer contribute to the value space" of the
