I am fully aware that this validator got "too big" now, and a separate repository containing the data would be better. However, that is also a tricky move (changing dependencies, making the DataLoader cross vendor or designing a standalone interface for the data).

I decided to just deliver it, since the bulk of it is easily removable (data folder) if we want to change course later.
