I agree that we should look for a cleaner solution. But at the moment we 
don't have one. It will take some time until we have a reasonable 
solution for this.

I started with an idea to tag all polygons created by the mp processing. 
But I think that's too complicated for the style file.
Please start a new thread where we can think about how the new tag 
handling of the mp processing and the connection to the style system 
should look like. I am happy if more than two of us (I don't have good 
knowledge of the style system) are talking about fundamental improvements.

Just for now I strongly recommend to use this patch until a better 
solution is ready to use.
