Hi Vaclav,
pretty strange, i don’t know if you are aware of it. But gpt 4.5 can manipulate mps xml files directly and correctly. I just tested twice. Unique ID s of are correctly handled and concepts are looked up in examples. In my examples, even the collection language was applied correctly to a problem ….
I also manipulated a dataux form of mine directly in a *.mps. Probably just need some sort of language export, or probably just the structure of the language as reference.
This solves my use case almost perfectly….
