-	This example demonstrates the AjaxTrigger component, which allows you to enqueue a series of updates to
-	occur.  Note that these happen in series as multiple requests, not as a single request, so you will want
-	to limit the number of updates you do in a single pass.
+	AjaxTrigger gives you multiple container updates in one series. This exmaple shows, how you can
+	achieve the same result in one RR cycle by supplying a NSArray of container ids (alternatively a 
+	comma separate string with multiple container ids). You see from the timestamps that all updates are generated at exactly the same time.
