These two things don't really go well together I believe. The Nedelec element ensures that the tangential component of solutions are continuous across faces, but not the normal component. Consequently, there is no way to easily enforce anything for the normal component of the solution at the boundary. Can you tell us what your bilinear form? (The typical use case for Nedelec elements is the curl-curl operator. If you multiply with a test function and integrate by parts, you'll get boundary terms as always, but none of the factors in these boundary terms have anything to do with the normal component of the variable, which also indicates that you can't impose anything on the normal component of the solution.)
