An action assertion is a statement that concerns some dynamic aspect of the business. It specifies constraints on the results that actions can produce. The constraints are described non-procedurally, in terms of the other atomic business rules. Where the structural assertions describe possibilities, action assertions impose constraints -- 'must' (or 'should') or 'must not' (or 'should not').
