The isset() check was odd and confusing. I think I added it in Ie572809 to be able to run the normalizer independend from the validator. But the "params" element is required anyway. It makes much more sense to enforce it in the normalizer as well. Even if this currently doesn't make a difference in real-world scenarios, it makes the code easier to read.
