We've removed the following sentence from the Immune/Protect entry in the REG:
Game rules do not apply to a card that is immune to or protected from the effect of the game rule.
The impact of this change is that cards which are "protected from discard" can now be discarded by decrease or by the numbers in battle. "Protection from discard" means "protect from discard abilities".
