But some nodes in the "highway layer" should be shared with the "boundary
layer", such as when a highway enters into a different jurisdiction and
gets a different name, max speed, etc. Also, in some cases the centerline
of the highway is legally the boundary between two jurisdictions, and in
that case all the nodes in the highway should be shared with the applicable
boundary .
