You can also draw a polygon with a LineSymbolizer (drawing only the
outline), so that is not the whole story of this rule. The other part
that is needed here is the actual query in the <Layer>, which is indeed
drawing from the planet_osm_line table.
So this one boils down to: mapnik will draw any linear barrier, that is
not a hedge, as a black line.
This is completely separate from the rendering of nodes, where it will
(as mentioned before) only render barrier=gate, nor of the completely
absent rendering of area barriers.

Good luck getting the Cycle Map stylesheets.
