Identities of conformal algebras and pseudoalgebras

For a given conformal algebra $C$, we write down the correspondence between identities of the coefficient algebra $\Coeff C$ and identities of $C$ itself as of pseudoalgebra. In particular, we write down the defining relations of Jordan, alternative and Mal'cev conformal algebras, and show that the analogue of Artin's Theorem does not hold for alternative conformal algebras.
