DAM: Only one TOTAL_OVER

[Wilson, Peter R]

    The DAM allows a maximum of one TOTAL_OVER constraint in a
SUBTTPE_CONSTRAINT. Is there any good reason why it should not allow
multiple TOTAL_OVERs?

    For example, our old friend person being either male or female and
either alien or citizen. At the moment this has to be done like (ignoring
any syntax errors):
SUBTYPE_CONSTRAINT sc1 FOR person;
  TOTAL_OVER(female, male);
END_SUBTYPE_CONSTRAINT;
SUBTYPE_CONSTRAINT sc2 FOR person;
  TOTAL_OVER(alien, citizen);
END_SUBTYPE_CONSTRAINT;

    Why not allow
SUBTYPE_CONSTRAINT sc12 FOR person;
  TOTAL_OVER(female, male);
  TOTAL_OVER(alien, citizen);
END_SUBTYPE_CONSTRAINT;
