A counter-example to my conjecture

I’ve found the following counter-example, to this conjecture:

Example For a set S of binary relations

\forall X_0,\dots,X_n\in S:\mathrm{up}(X_0\sqcap^{\mathsf{FCD}}\dots\sqcap^{\mathsf{FCD}} X_n)\subseteq S

does not imply that there exists funcoid f such that S=\mathrm{up}\, f.

The proof is currently available at this PDF file and this wiki page.
