-    rank: |
-        The POIs are ranked ascending according to their importance within a grid. The `rank` value shows the
-        local relative importance of a POI within it's cell in the grid. This can be used to reduce label density at *z14*.
-        Since all POIs already need to be contained at *z14* you can use `less than rank=10` epxression to limit
-        LMs. At some point like *z17* you can show all LMs.
