[OSM-dev] Are there a feature rendering rules for Mapnik?

Hi,

I took a closer look now and it is really neat, but I don't understand  
this:

minor-roads
	minor-roads-casing		
5 000	1 000		
☡
([highway] = 'secondary' or [highway] = 'secondary_link') and not  
([tunnel]='yes' or [tunnel]='true')
	CSS:
		stroke:	#a37b48 stroke-dasharray:	 stroke-linecap:	round stroke- 
linejoin:	round stroke-width:	17;
		
	minor-roads-fill			
5 000	1 000		
☡
([highway] = 'secondary' or [highway] = 'secondary_link') and not  
([tunnel]='yes' or [tunnel]='true')
	CSS:
		stroke:	#fdbf6f stroke-dasharray:	 stroke-linecap:	round stroke- 
linejoin:	round stroke-width:	14

Where is the difference between "fill" and the "casing"? The  
conditions are the same, aren't they?

What do I miss here?

Thanks
Ivo
