Pieren, is there an example of confusion actually being caused? > Please think > as a contributor, not as QA programmer or data consumer (it's easy to > check if the speed limit belongs to a waterway or not). It's easy to think up potential for confusion whichever way we go on this. Thinking as a contributor, the editing interfaces should make it clear which units the user is stating/implying - as iD does, for example. I definitely sympathise with Tom's reasoning for one unit per tag, so I'd suggest there would need to be a strong case for this mixed-units approach...
