An algebraic mechanism of generation of such dynamics is explored on simple "toy" examples and models. Nonpotential chains and their continuum limits are also considered. Examples of hybrid couplings with both potential and nonpotential (magnetic--type) interactions are discussed.AMSTEX 9 pages, a slightly revised versionExactly Solvable and Integrable Systemstext
