+
+	* src/main/java/de/intevation/flys/exports/IntegerAttribute.java: New.
+	  Concrete subclass of a DefaultAttribute for storing integer values.
+
+	* src/main/java/de/intevation/flys/exports/LegendSection.java: New. A
+	  concrete Section subclass to store legend specific attributes.
+
+	* src/main/java/de/intevation/flys/exports/BooleanAttribute.java,
+	  src/main/java/de/intevation/flys/exports/StringAttribute.java: Removed
+	  needless import of org.w3c.dom.Attr.
+
+	* src/main/java/de/intevation/flys/exports/ChartSettings.java: ChartSettings
+	  is able to store a Section for legends now.
+
+	* src/main/java/de/intevation/flys/exports/XYChartGenerator.java: Added
+	  methods to retrieve the font size of legends and if the legend should be
+	  visible or not. In addition, the ChartSettings returned by this instance
+	  will now contain a LegendSection as well.
