quite. the format for ref in relations is very clear, for example

Don't think this is clear. US:I is wrong, the network is only I. Any
consumer application can figure out that it is in US by itself. as an
example mkgmap currently supports custom shields and does it based on
the way refs. But with US:I an application has to filter the US:
specifically for this kind of network which isn't used anywhere else.
if you think the state, country info is needed as a tag use is_in or
an addr:* tag
combining different values in a single tag makes it too complicated to
consume data.
there is a major disconnect between what people think is "right" and
what the wiki calls for. from
http://wiki.openstreetmap.org/wiki/Interstate_Highways_Relations
we see:
network=US:I, US:I:BUSINESS, US:I:DOWNTOWN, US:I:FUTURE Required.
Business, downtown and future routes have their own signage
and
ref=* Required. ex. 90
and many people have been busy building relations to fit this specification.
from
http://wiki.openstreetmap.org/wiki/United_States_Numbered_Highway_Relations
network=US:US
ref=* ex. 20
and so forth.
