I’ve also struggled with this before as you can see if you search the mailing list. My question: https://www.mail-archive.com/ntg-context@ntg.nl/msg97763.html Wolfgang’s answer : https://www.mail-archive.com/ntg-context@ntg.nl/msg97775.html We should probably change the wiki to make it clear that no inheritance of environments happens here. Denis Von: ntg-context Im Auftrag von mastermind_ x Gesendet: Mittwoch, 9.

The wiki didn’t say that. Plus it is already specified at the product level. Thanks. ~Jethro
