I think I'm done.
Tried to avoid fixtures that are already included or Chinese ones. If I didn't miss anything, they all pass the validator.
Please note, that I did not exactly reviewed the correctness of every single definition because of a lack of experience creating fixture definitions. However I did a short check for every fixture definition if it roughly matches the manual.
In addition to that, I'm not quite sure if I covered all the threads you haven't processed yet, since there where some, that you've already added.
From time to time I can look back in this section and report new fixtures in here.
If you need further help/information, please let me know.
