In http://www.mkgmap.org.uk/pipermail/mkgmap-dev/2010q2/008276.html I have noted that there is one shortcome in the multipolygon code. It checks if the mp is tagged with a polygon tag. In that case the tags are copied from the mp otherwise are copied from the element ways. The problem is that the mp code has a (too short) static list of polygon tags (boundary, natural, landuse, land_area, building, waterway). Now my question (to Steve?): How can I get a dynamic list of polygon tags referenced in the style? I need it in the Osm5XmlHandler from where I can give it to the MultiPolygonRelation objects. Have fun! WanMil
