+	* doc/conf/conf.xml: Added a config section for floodmaps. Currently, the
+	  background layer's url and layername is defined here.
+
+	* src/main/java/de/intevation/flys/artifacts/states/WMSBackgroundState.java:
+	  Read the background layer configuration from conf.xml. Those values are
+	  used to create the WMSLayerFacet.
