17737	Unclear scope of mapcss class (set clause)	GerdP	team	"We have rules like this in geometry.mapcss
{{{
#!mapcss
way[highway][area!=yes][!tunnel][!covered] > node {
  set node_in_highway;
}
}}}
I wonder if we have any rules regarding the scope of the class node_in_highway?
It seems that anybody assumes that the scope is limited to the *.mapcss file where it is used.
IIGTR the current implementation in MapCSSTagChecker neither cares about it not does it make sure that the rule sets in different *.mapcss files are executed in any particular order. So, what is the expected result if two *.mapcss use the same class?
