Working with Timer Nodes

TIMER NODES PRESENT IN WMB ARE :

1.TIMER NOTIFICATION NODE,

2.TIMER CONTROL.

WE CAN USE TIMER NOTIFICATION NODE INDEPENDENTLY BUT WHEN WE USE TIMER CONTROL NODE  WE SHOULD USE TIMER NOTIFICATION NODE.

WE CAN USE  TIMER NOTIFICATION NODE WITH MULTIPLE TIMER CONTROL NODES.(i.e ONE  TIMER NOTIFICATION NODE AND ONE OR MORE TIMER CONTROL NODES.)

WHEN WE USE  TIMER NOTIFICATION WITH  TIMER CONTROL  "UNIQUE IDENTIFIER" SHOULD BE COMMON WHICH IS COMMON PROPERTY FOR TIMER NOTIFICATION AND  TIMER CONTROL NODES.
