I don't really think we can just take that classification and apply it to OSM. It may not look like it from the map in that file, but it would make Flanders almost void of primary roads. Our government isn't very keen to give lots of roads a primary status. And all the dead-end primary roads won't give a nice map either (ringway of Lier without any primary road connecting to it, things like that). I've been aware about the official classification (read some previous discussions in the mailing list archive), but I think we at least need to include some secundary classified roads tagged as primary in OSM to make a useful map. So far, we don't have a list of those. In the UK, the category of official primary roads would be tagged as trunk in OSM. That said, using road numbers to determine OSM classification is actually how it's done in most countries. It's not perfect by far but we've always allowed some deviations from the rule where it makes sense.
