Fix issue with non-scalar sections. Introduce possible solution.

Intuitively, you have to do some integration by parts to get rid of 'derivatives of $\phi$' and then whatever will multiply $\phi$ has to vanish, which will produce the Euler-Lagrange equations. The paper arxiv.org/abs/1406.3369 provides integration by parts formulae for expressions involving jet prolongations. | |
