The resulting symbolic expression must contain a different sort of
information. For example
∂²f/[∂J(x1)∂J(x2)]
does not have a analogon, if you try to dervive it in terms of ordinary
differentiation with subsequent substitution. Structurally, for the
functional derivative, you must basically b

Typo: All the "g"s are supposed to be J's, sorry.
