univ\] Let $\bB$ be a bivariant theory on $\m V$ such that a smooth morphism $f: X\to Y$ has a stable orientation $\theta(f)\in \bB(f)$. Then there exists a unique Grothendieck transformation $$\ga:=\ga_{\theta}: \bM(\m V/-) \to \bB(-)$$ satisfying the normalization condition that for a smooth morphism $f:X \to Y$ the following identity holds in $\bB(X \xrightarrow {f} Y)$: $$\ga([X \xrightarrow {\op {id}_X} X]) =  \theta(f).$$
