Underspecified Modelling of Complex Discourse Constraints

We introduce a new type of discourse constraints for the interaction of discourse relations with the configuration of discourse segments. We examine corpus-extracted examples as soft constraints. We show how to use Regular Tree Gramamrs to process such constraints, and how the representation of some constraints depends on the expressive power of this formalism.
