Since I can't make a suggested edit, I'll make my suggestion here: please explain CHF as Swiss francs; unlike most other countries, the two letter code is not enough to guess the country name. Looking it up, it seems to be the country's name in Latin, which led me into a Wikipedia rabbit hole that ended say the Spanish Reconquista before I realized what I was doing.

The PDF standard is another standard that is locked up, despite the earlier versions being fully open before Adobe gave it up.
