Internals from elaboration

Elaboration or Narration, as so-called discourse relations (or rhetorical relations), are modelled in Segmented Discourse Structure Theory (SDRT) as relations between discourse constituents (or constituents for short). These are either propositions that come into being by interpretation of sentences occurring in a text; the propositions then have the status of DRSes. Or, constituents are compounds of such DRSes, constructed from DRSes (or compounds of them) by discourse relations. Elaboration and Narration in that sense, rather than referring to text types, provide links between constituents that allow them to combine in ways that, for a recipient, a resulting text is coherent and has (some) elaborative or narrative properties.
