+###### Override News Feed settings with flexform settings from requested page
+
+Most of our news plugins come with a flexform checkbox field called "useForRSSFeed".
+If a user opens a page in the frontend with the pagetype attached ("/news.xml") and the page contains a news plugin
+(or multiple), the default newsFeed configuration can be overwritten by the flexform settings on the page.
+The first plugin on the page, where the checkbox "useForRSSFeed" is checked, is used to overwrite the configuration.
