Hmm. What is the application for? How would you model it as a bunch of interacting objects? Can you give a short user story for the application you are trying to create?
What is making you feel uncomfortable about having a class for the parameters? What would make you feel comfortable instead?
I usually get a feeling of discomfort when the code is fighting me. The solution is to think about responsibilities.
Usually the class that owns a parameter is the best place to put the responsibility of dealing with it. If you have classes that are constantly asking others for info then the responsibilities are probably in the wrong place.
Hth,
