When fixing DFDL-808, some tests were modified so they would work again, but due to DFDL-809, the style of those tests puts some assertion checking in a place that is non-obvious and unituitive.
This JIRA issue is to revisit these tests, and move the asserts to the natural place (on the element declarations, not the element references to them.)
The tests are
test_nested_patterns_02
test_regexLookaheadFail
test_nested_seq_01
test_nested_seq
test_litNil6
