The XXZ spin-chain Hamiltoman has been constructed to be su(2)q-invariant, but naively does not appear to be su(2)-invariant. However, using recently discovered deforming maps between representations of su(2)q and corresponding representations of su(2), we prove a theorem which states that if a Hami
