Highway refs are often indicated by route relations, so we need to support them. One relation may be part of multiple road route relations, each of which has a ref...
The water polygon layer currently requires `way_area`. This implicitly prohibits unioning the water areas, a standard method of reducing tile size. We should not require way_area.
The description to `railway=rail` in the `streets` layer says > ways with [service](https://wiki.openstreetmap.org/wiki/Key:service)=* on zoom level 8+, other ways on zoom level 10+ For railways service is yard, spur, siding,...
a highway=motorway_link gets kind=motorway link=true in the streets layer, while in the street_label layer it gets kind=motorway_link. This is inconsistent and makes it more confusing to write styles.
The streets layer states > More important roads are are sorted before less important roads, tunnels before bridges Not just roads are in the layer - aeroways and rails are...
Looking at the streets and street_polygon layers, they are inconsistent on their use of field not available vs empty string. for streets you have tracktype and service defaulting to no...
Ways with both highway tags and railway tags have been a [long-known issue with some styles](https://github.com/gravitystorm/openstreetmap-carto/issues/874). CartoCSS-based style had to combine railway and highway into one column to avoid [suboptimal...
The information whether a road is accessible to the general public is currently missing from the vector tiles. It would be convenient if the access restrictions would be conflated somehow,...
There are several issues with the documentation of the `boundaries` layer: 1. `admin_level` property is defined as `numeric`. I believe this should be clarified as unsigned integer (see also #31)...
The [boundary_labels layer](https://shortbread.geofabrik.de/schema/1.0/#layer-boundary_labels) says the area is measured in `ha`, i.e. hectare. Other layers use `area in square meter (Mercator Projection)`. Either one or the other is wrong or it...
