I might be missing something here but I can't find a way to track whether a spell is castable due to lockout?

For example, I'm making a predictive icon for moonkin which decides which spell I should be casting (lunar strike/solar wrath) based on current state of eclipse buffs, but it would be good to stop a spell from displaying if that school is currently locked. 

Hopefully I'm just missing something obvious.

School locks are treated as a cooldown on the affected abilities. This isn't unique to TMW - this is just how they're handled by the game.
