  A higher spin field theory on AdS(4) possesses a conformal field theory on
the boundary R(3) which can be identified with the critical O(N) sigma model of
O(N) invariant fields only. The notions of quasiprimary and secondary fields
can be carried over to the AdS theory. If de Donder's gauge is applied, the
traceless part of the higher spin field on AdS(4) is quasiprimary and the
Goldstone fields are quasiprimary fields to leading order, too. Those fields
corresponding to the Goldstone fields in the critical O(N) sigma model are odd
rank symmetric tensor currents which vanish in the free field limit.
