An opponent can not "target" Uril, however it can be enchanted with some tricky tricks like having an enchantment on the battlefield like Control Magic and then playing Copy Enchantment and choosing to copy the Control Magic and then choosing Uril to enchant with the copied Control Magic. This works because the Copy Enchantment never targets Uril.
Here's the Gatherer Card Ruling: 10/1/2005: If you choose an Aura, you also choose a legal permanent for the Copy Enchantment copy of it to enchant. Copy Enchantment doesn't target that permanent, however, so it can enter the battlefield attached to an untargetable creature.
