A classification of soliton solutions is proposed for a number of completely integrable field equations when the solutions correspond to states periodic with respect to one variable but self-localized with respect to the other. The classification is based on the characteristic structure of the singular (separatrix) solutions of a dynamical system in infinite-dimensional phase space.
