This is the first I've heard of this tag. I don't recall it being
discussed when we were hashing ideas around on this last summer. (Not
that that is reason to discount it.)

But what came out of that discussion was the following guidance: "ref"
will store "the unique identifier within a particular classification",
where "particular classification" is stored wholly in the "network" tag.

So, "network=US:US:Business"/"ref=13" and "network=US:US:Truck"/"ref=70"
both conform to that definition.
"network=US:US"/"modifier=Business"/"ref=13" does not.

Are "US:US:Business" and "US:US:Truck" "true" networks? Perhaps not.
Would it be "correcter" to separate "truck" and "business" into other
tags? Perhaps. Is storing "business" and "truck" within the "network"
tag causing confusion for data consumers and not a workable solution?
Doesn't look like it from the proof of concept renderer posted on here.

Agreed...good points.
