i agree, it's a rendering prefix for a ref tag value and deserves
its own, separate tag.

i've seen an argument that the correct network value for a county
route involves using the actual county name, e.g.

network=US:NY:Albany

rather than a more generic CO, CR, CH or what have you, and i
find i can't really argue against that. using the generic value means
you can't distinguish between CR 1 in Albany County and CR 1 in the
adjacent Rensselaer County based on the network and ref tags.
