In a top-down approach to discourse analysis, the first step is to develop the analytical framework, determining the set of possible discourse unit types based on an a priori determination of the major communicative functions that discourse units can serve in these texts. That framework is then applied to the analysis of all texts in the corpus. Thus, when texts are segmented into discourse units it is done by identifying a stretch of discourse of a particular type – that is, that serves a particular communicative function. Once
