The non-equilibrium dynamics of domain wall initial states in a classicalanisotropic Heisenberg chain exhibits a striking coexistence of apparentlylinear and non-linear behaviours: the propagation and spreading of the domainwall can be captured quantitatively by \textit{linear}, i.e. non-interacting,spin wave theory absent its usual justifications; while, simultaneously, for awide range of easy-plane anisotropies, emission can take place of stabletopological solitons -- a process and objects intrinsically associated withinteractions and non-linearities. The easy-axis domain wall only has transientdynamics, the isotropic one broadens diffusively, while the easy-plane oneyields a pair of ballistically counter-propagating domain walls which,unusually, broaden \textit{subdiffusively}, their width scaling as $t^{1/3}$.
