+    data (such as Repeater).

+    Here is an example of a model containing news from a Yahoo RSS feed:
     \qml
     XmlListModel {
         id: feedModel
         source: "http://rss.news.yahoo.com/rss/oceania"
         query: "/rss/channel/item"
         XmlRole { name: "title"; query: "title/string()" }
-        XmlRole { name: "link"; query: "link/string()" }
+        XmlRole { name: "pubDate"; query: "pubDate/string()" }
         XmlRole { name: "description"; query: "description/string()" }
     }
     \endqml
-    \note The model is currently static, so the above is really just a snapshot of an RSS feed. To force a
-    reload of the entire model, you can call the reload function.
+
+    You can also define certain roles as "keys" so that the model only adds data
+    that contains new values for these keys when reload() is called.
+
+    For example, if the roles above were defined like this:
+
+    \qml
+        XmlRole { name: "title"; query: "title/string()"; isKey: true }
+        XmlRole { name: "pubDate"; query: "pubDate/string()"; isKey: true }
+    \endqml
+
+    Then when reload() is called, the model will only add new items with a
+    "title" and "pubDate" value combination that is not already present in
+    the model.
+
+    This is useful to provide incremental updates and avoid repainting an
+    entire model in a view.
