Thanks for correcting me, I could easily have tested that. (And significant white-space should perhaps be limited to tabs in Python).

As a better alternative, could a single "!" be required to set a normal priority, such that providing only a property value would not affect priority at all? That is: "style.property = value{!{important}}" ? 
The absence of "!{important}" would then be similar to the absence of a priority argument to "setProperty", with exactly the same effect.
Or would it be better to leave that part of the spec alone?
