Warning for style "Universität Bern - Institut für Musikwissenschaft (note, Deutsch)"
When I add the the style "Universität Bern - Institut für Musikwissenschaft (note, Deutsch)" style to Zotero (via the official styles menu), I get the message box that the style is not a valid CSL 1.0.1 style. I've seen this issue (https://github.com/zotero/zotero/issues/2341) and the linked discussion (https://forums.zotero.org/discussion/comment/399020/#Comment_399020). I understand that the new terms aren't supported yet, but 1. I don't think the style uses any of those, and 2. the style comes from the official repo, so it should be valid, right? What am I missing here?
2. The official repo is 1.0.2 compatible, as it says at the top of the repo page.
