All polygons created by the multipolygon algorithm are tagged with 
mkgmap:stylefilter=polygon, which means that such tagged ways are only 
used with the polygon style. The source ways of the multipolygon are 
tagged with mkgmap:stylefilter=polyline, so that they are only handled 
by the line style. This allows to visualize boundaries although the 
boundary multipolygon is not fully contained in the tile.

 From my point of view, the area tag is relevant for tags that could 
either be used as line or as polygon. If you create a square tagged with 
highway=pedestrian the place inbetween could either belong to the 
pedestrian area (area=yes) or could be not accessible (area=no or not 
set). But I admit that the area tag was used in multiple variants and I 
am not a very up2date in OSM tagging guidelines.
