+// Code from http://www.wpfmentor.com/2009/01/how-to-debug-triggers-using-trigger.html
+// No license specified - this code is trimmed out from Release build anyway so it should be ok using it this way
+
+// HOWTO: add the following attached property to any trigger and you will see when it is activated/deactivated in the output window
+//        TriggerTracing.TriggerName="your debug name"
+//        TriggerTracing.TraceEnabled="True"
+
+// Example:
+// <Trigger my:TriggerTracing.TriggerName="BoldWhenMouseIsOver"  
+//          my:TriggerTracing.TraceEnabled="True"  
+//          Property="IsMouseOver"  
+//          Value="True">  
+//     <Setter Property = "FontWeight" Value="Bold"/>  
+// </Trigger> 
+//
+// As this works on anything that inherits from TriggerBase, it will also work on <MultiTrigger>.
