I cleaned up the LaTeX a bit and added links. I fixed the grammar I broke by adding links, and also fleshed out the argument a bit.

Oct 2, 2014 at 1:31 comment added user27920 Local freeness is not sufficient: it must also have the "correct" rank (related to the fiber dimension). After all, if $k'/k$ is a finite extension of fields then $\Omega^1_{k'/k}$ is a $k'$-vector space of finite dimension but is nonzero when $k'$ is not $k$-smooth (equivalently, not $k$-etale).
