I get an error when I try to use an InList in a conditional node. Same holds true for ETFAssetClass and other taxonomy functions.

Boolean rules should be placed into a custom universe, given that you’re working with a ranking system. You can also pipe a ranking system through a screen or portfolio to apply a true/false rule.
Ranking systems don’t have universes until they’re used, so you can’t use InList in them. (You don’t know whether a ticker is true or false until you see whether it’s in the universe.)
The ETFAssetClass factor and its ilk are qualitative, so the output of a ranking would be nonsense. (Do you rank bonds over real estate but under equities?)
