Since Ivan's reasoner and my RL testcases both closely resemble the RL ruleset, bugs in the RL-part of the testsuite should be easy to detect by such a comparison (unless Ivan and I made exactly the same errors independently): If Ivan's reasoner fails on one of my tests, than either his implementation or my testcase must be wrong; this can then be checked visually and fixed. And I have already checked that there exists (at least) one testcase per RL rule (first by design, and later by an additional audit of the whole testsuite).

These are the testcases that cover all the tables in the RL spec except for the datatype table 8. I think, the datatype table should still be covered coarsely, but it's not necessary to check all RL datatypes.
