I also prefer "class" or "type" keys.


One of the problem I see in the highway/railway/etc scheme is that the 
key is no more just a key, but hold information in itself. It's 
certainly a good thing for concision (is it a real english word?), but 
not for consistency and ease of processing or ui things.

I strongly prefer something like
type=road class=primary
type=rail class=secondary

than
highway=primary
railway=secondary


I see three big advantage for the Map_Features system :
- It is documented on the wiki
- Andy has done work to make it as complete as possible
- osmarender "default" rules file use it.

But I don't like it.


Another big problem to keep in mind for people searching for the best 
tagging system is the "roundabout problem". A junctions can be road, 
rail, etc. and it can be primary or not... I like the idea of clearly 
tagging junctions, because it can help an automatic simplification of 
maps at higher level.
