Sure, the entities would make things somewhat easier. But the XML is still horribly to work on. Steve gets all my sympathy :-). (btw: in case you haven't seen this, I created a XSL style file to turn Mapnik XML into HTML. See http://geo.topf.org/mapnik/osm.xml for an example. Makes working with large Mapnik map files somewhat easier.) But I'd rather have a GUI editor. Artem started on one but it seems its more or less abandoned now. Steve Coast showed one slide at SOTM with something that looked like a Mapnik style editor or similar. I meant to ask for details but forgot. Is there something coming up there?
