A wall of this kind is a composite object consisting of three elementary topological defects: two edge defects with winding numbers -1/2 and a vortex with a winding number +1 between them. We provide a qualitative model accounting for the energetics of such a domain wall.3 pages, eps figures. Proceedings of MMM 05Mesoscale and Nanoscale Physicstext
