That is an absurd proposition.  It could lead us to label them as 
"vägklassning=riksväg ; vägbredd=9 meter ; hastighet=90 km/h" and 
we should just ignore the fact that the map of Sweden doesn't get 
rendered at all.  I feel like I have been far too pragmatic in my 
first three years of OpenStreetMap.

It's all very easy.  The function is "riksväg".

There are non-motorway roads where tractors and bicycles are 
disallowed.  These are called "motortrafikled" (and "2+1 väg") but 
they are not very common in Sweden.  And I don't know if this road 
type is ever indicated on printed maps.
