+	* src/main/java/de/intevation/gnv/artifactdatabase/client/ArtifactDatabaseClient.java,
+	  src/main/java/de/intevation/gnv/artifactdatabase/client/DefaultArtifactDatabaseClient.java:
+	  Added 'doAdvance' method to be able to advance only - without feed or
+	  describe. We need this method to step back to previous states. Advance was 
+	  bundled with feed and describe, before.
+
+	* src/main/java/de/intevation/gnv/action/sessionmodel/SessionModelFactory.java:
+	  Some code refactoring.
+
+	* src/main/java/de/intevation/gnv/util/XSLTransformer.java,
+	  src/main/java/de/intevation/gnv/action/NextArtifactStepAction.java: Set
+	  parameter of xsl transformer which contains the url to step back to a 
+	  previous state. This parameter is used in xsl sheet to render a
+	  link into the user interface.
+
+	* src/main/java/de/intevation/gnv/action/PreviousArtifactStepAction.java:
+	  New controller to step back to a previous state.
+
+	* src/main/webapp/WEB-INF/config/struts-config.xml: Added a new action which
+	  calls PreviousArtifactStepAction to step back to previous states.
+
+	* src/main/webapp/WEB-INF/config/templates/describe-ui-static.xsl:
+	  Refactored gui rendering. The static part of the parameter list is
+	  rendered in a table with three columns (icon to step back, parameter name,
+	  selected value). The target state to step back to is contained as
+	  attribute 'art:state' in 'xform:select', 'xfom:select1' and 'xform:group'
+	  nodes.
+
+	* src/main/webapp/styles/default.css: Added a style class to adapt the first 
+	  column of the static part's table.
