+	Use artifacts configuration (e.g. winfo.xml) to define which facets
+	can be used in which output. Hide no-matches.
+
+	* src/main/java/de/intevation/flys/collections/AttributeWriter.java,
+	  src/main/java/de/intevation/flys/collections/FLYSArtifactCollection.java:
+	  Added use of "compatibility matrix". Only include facets in in
+	  collections description document that are marked compatible in the
+	  masterartifacts configuration (e.g. winfo.xml).
