We consider the following problem: Characterize the pairs $\langle A, B \rangle$ of subsets of ${\mathbb R}$ which can be separated by a function from a given class, i.e., for which there exists a function $f$ from that class such that $f=0$ on $A$ and $f=1$ on $B$ (the classical separation property) or $f0$ on $A$ and $f>0$ on $B$ (a new separation property).
