I've done some calculations of magnetostatics coupled with other problems,
but there are quite a few limitations at the moment. Most notably we don't
have complex valued shape functions, which you'd need for time harmonic
Maxwell. Also, projections don't work yet for Nedelec elements (meaning no
DirichletBoundary, adaptivity, etc).

First order, type 1 Nedelec elements are implemented for quads, triangles,
and hexes. Tets have been on my TODO list for awhile now (and keep getting
buried...). I don't foresee higher order coming any time soon, but we'd be
willing to guide you in implementing any of these features.
