Ian has suggested the established is_in= tag for this purpose, and Alex
Mauer has suggested a relation that contains all the routes for a (state
or lower) network.

Personally, of those two, I think I prefer is_in=.

Keep in mind that any tagging we do needs to be compatible with global
usage, and network= is already in use.  I'd suggest something along the
lines of "US:State" and "US:County" to fit in with "US:I" and "US:US".
(And also to continue keeping our own namespace for values.)
