Two reasons, so far.  We have found highways maintained outside the
border of the expected jurisdiction.  So a NY shield is required in
Pennsylvania.  But mostly because we have to describe the shield in
the context of a file system, as well, to find the shield images.
Finding the M shield is easier when we know if it should be the AU_M,
UK_M or another.

We're not describing the jurisdiction, but the network, or essentially
the shield background image.  It can't always be extracted from the
location.
