I agree with the principle here @JimBiardCics Myself, I'd put less onus on the checker, as long as the variables exist, I'd let this pass. I expect this to be the limit of the current conformance expectations. Checking for matching dimensionality, standard name, units and so on feels to me (at first glance) like adding complication to the checker that is difficult to encode to meet all cases. A balance between good protection and minimal false alerts may be difficult to strike in these cases, I fear. As always, 'What is proportionate?' is a useful detail aspect for us to reach consensus on within this ticket and I welcome this aspect of the discussion. cheers mark -- You are receiving this because you are subscribed to this thread.
