ideally the renderer can figure out everything based on the ref tag  
and some tag or intelligent location lookup to find the state, county  
a road is in.
  It contains all you need to pick the correct sign. But you need the  
whole knowledge about signs for all states, county ...
as an example California uses different signs for US routes but the  
same for interstates. State, county signs are different everywhere.  
And hey there is a world outside of US with even more variants. they  
will love local signs too!
Adding a symbol tag is some work but doesn't harm if someone comes up  
with a heuristic in the renderer based on the ref, network, is_in,  
addr* tags and ignores it.
a planet file is 102G uncompressed! does anyone care if we add ~ 1000  
symbol tags for US?
