[OSM-talk] Mapnik rendering questions

[Maarten Deen]

I have two questions about some Mapnik renderings I encountered on the 
main OSM map.

1)
Why is this road not rendered as a tunnel?

This is not a general error in the sylesheet, see this road which is 
rendered as a tunnel.

2)
When rendering public transport platforms, the layer tag does not seem 
to be taken into account, making platforms that are areas render below 
roads that are running under the platform.
Example: http://www.openstreetmap.org/way/222561489 but there are a lot, 
like here https://www.openstreetmap.org/way/442106261
This probably is a bug in the stylesheet?

Maarten
