I copied and pasted from the wrong source! So, in any case, the signature would match in your evaluations. This is part of the reason why I'm doing this... to see just how hard it is to do the claims and evaluate manually. Not that easy to do correctly at least when your new at evaluating apparently. But we'll design tools to make it easier for a manual verification before we design the automated tool.
