If that's the distinction, IMHO that would be better expressed other ways: For a "winter road":
highway=track (or path, or whatever else best represents its quality in summer) winter_road=yes For an ice road: winter_road=yes So, to know what it's like in summer, you ignore the "winter_road" attribute: the ice road is nothing at all. To know what it's like in winter, you look primarily at winter_road=yes. If that's set, then you can ignore other properties like highway=yes. This also has the advantage that any renderer/software that doesn't know about winter roads will err on the side of caution by not showing anything at all in some cases. Where life may get complicated is when a way ends up with two names. Say, a name for a 4wd track, and a different name when it's a winter road. A route relation might be the best option there.
