Note that we are not supporting anything less than ENDF/B-VII.0 and the ENDF format that it used. So any feature that relies on this does not have to be checked. In fact, an exception should be thrown if discovered. Also, we are only backwards compatible with NJOY2016—not NJOY99.
This means that we only have to check cards 1–3. It also means that card 3 is required.
