Division of the 14 parasegments of the embryo into anterior and posterior compartments; exemplified by the actions of the segment polarity gene products. The regionalization process that divides the spatial regions of an embryo into serially repeated regions. The hierarchical steps resulting in the progressive subdivision of the anterior/posterior axis of the embryo. The pattern specification process by which an axis or axes is subdivided in space to define an area or volume in which specific patterns of cell differentiation will take place or in which cells interpret a specific environment.
