Hi Marek We have been around this loop before. The problem with putting in a more specific compatible is that nothing is validating it. So it is going to be wrong, simple because people cut/paste, and don't necessary change it. So when we do need to look at it, we cannot look at it, because it is wrong. I would only add a more specific compatible if and when we need it, it is actually used, and we can verify it is correct. Andrew
