I'm going to be prescriptive and say that you meant "prescriptive" rather than "proscriptive".

"Prescriptive" means "requiring" or "normative, specifying, prescribing", while "proscriptive" means (more specifically) "forbidding". It has only a negative sense of saying something is not allowed, while "prescriptive" includes a broader sense of specifying or ordaining something in any way.

I was going to argue, but, yeah - that makes sense.
