It should definitely support any type bit<W> for W ranging from 1 up to some implementation-dependent maximum width.

While there might some small convenience in supporting types int<W>, if an implementation did not support that, it would not be difficult to take a random value of type bit<W> and cast it to int<W>, perhaps performing an addition or subtracting on it to get it in the desired range.
