I've been working on this rendering and I'd suggest the reverse of this 
for the condition as it is easier to implement in mapnik.  It would 
produce the same result so I put it up as a tip for anyone wanting to 
implement this.

Any thing that has 
surface=unpaved/dirt/sand/gravel/fine_gravel/earth/compacted/clay/grass/pebblestone/ground 
is rendered with the dashed line/casing and all others are rendered as 
normal.
