They represent -- individual usage paradigms in-the-small. -- -- -- CHANGE HISTORY: -- 06 Dec 94 SAIC ACVC 2.0 -- 10 Apr 94 SAIC Modified comments in a subtest failure message. -- 06 Nov 95 SAIC Corrected subtest results for ACVC 2.0.1 -- 14 Mar 01 RLB Added checks that the lower bound is 1, similar -- to CXA4005.
