scalar  = FiniteElement("CG", triangle, 3)
vector  = VectorElement("CG", triangle, 3)

#element = scalar
#element = scalar["interval"]
#element = scalar[interval] + scalar
element = vector[interval]

v = TestFunction(element)
u = TrialFunction(element)

a = inner(grad(v), grad(u))*dx

They should all work.

evaluate_basis and evaluate_basis_derivatives is not implemented for restricted
elements. The reason is that I'm not sure about what should happen when I throw
away basisfunctions.
