Be careful. This is where many contributors get confused. The name of
the *path* is often not the name of the *route*. A route relation can, &
often does, go along paths with different names. Multiple routes can go
along a path.

It renders the names of the paths, not the routes.

Surface has no place in a route relation as it refers diectly to the
path, not the multiple relations passing along it. Similar for the
source tag.
