+    in a similar fashion as the property watch directive.
+
+    The event callback creates the event D-Bus object with the given name
+    and the event message.
+    eg /xyz/openbmc_project/events/test/<id>'
+  class: callback
+  callback: event
+  paths: example path group
+  properties: example property group

+  eventMessage: "Test configuration changed."
