Forum:Xyz Material Rulings vs. Numbers F0 and S0

Number F0: Utopic Future and Number S0: Utopic ZeXal both require Xyz monsters to be their materials for an Xyz Summoning, but it neither card states what happens to the original Xyz monsters' Xyz materials. Do they also attach to the new Xyz monster or do they go to the graveyard?
