Hi Rob, Am Samstag, 18.

Which I guess makes sense for a warning, since there seem to be a few preexisting ones. The warning itself was somewhere in the scrollback because I let dt_binding_check check all the files. So I learned I have to actually look at the output to see if there are any warnings. Cheers, Stefan
