If one line represents more features, it should be realy only one line in 
GIS, unfortunately we cannot mix more area layers in one map. If your 
municipal boundary would be road (as line) or river centerline, it could be 
represented by one line in one vector. I know that it is not solution for the 
problem you are talking about.
