Official Rulings for Planar Void
10/4/2004 : The card does go to the graveyard before it is exiled, so other triggered abilities will trigger on the card going to the graveyard.
5/1/2008 : It will not trigger on itself going to the graveyard, or on any other cards going to the graveyard at the same time. This means that neither itself nor other cards put into the graveyard at the same time as it will get exiled.
