[OSM-newbies] Why doesn't landuse:residential show up?

[Udo Giacomozzi]

Can somebody explain to me why the landuse:residential area doesn't
get rendered here?
http://www.openstreetmap.org/?lat=46.26835&lon=11.22325&zoom=17

Mapnik and Osmarender seem to ignore the area but "NoName" shows it. I
even tried adding a relation but apparently there is something wrong.

Also, for some strange reason Mapnik does not show the closed path
symbol (which can change the from clockwise to counter-clockwise and
vice versa). However, I double checked it and the path *is* closed.

What am I doing wrong?
