Just for fun: http://en.wikipedia.org/wiki/Pathological_(mathematics)
Maybe the problem is trying to validate against the archetype at first and then validate the IM. I think it should be IM 1st and AM 2nd. But of course, I may overlooked some pathological case and this might not work on 100% of the cases. I don't know why you call it pathological, as if it has to do with humans, something with freaks who want to crash systems, it can surely be the case. But more likely is a system which has a bug, and creates a faulty dataset. A "pathological" dataset can be the result of a buggy system. -------------- next part -------------- An HTML attachment was scrubbed...
