It appears that in France, the route numbering stops inside big cities 
(especially Paris), so while the N13 (which I would classifiy as 
highway=trunk) approaches Paris in the direction of Avenue des Champs 
Élysées, the road numbering seems to stop at the Pérephérique at Porte Maillot.

Personally, I would use highway=primary;lanes=4 for Avenue des Champs 
Élysées. It's a very wide road, and we've got Napoleon to thank for that one.

It seems that the N15 retains its route number right through Rouen, so it 
looks like the Government of France have different rules for Paris than the 
rest of France.

In the UK, it's reasonably easy, since most roads are given a designation by 
national or local government, even within towns.

I'm not sure about Spain. I've never been there.
