The paper focuses on the problems and possibilities of the annotation of interpropositional discourse relations in a dependency corpus of a natural language (Czech) such as PDT 2.0. Apart from the general introduction to the existing PDT 2.0 material and the relevant terminology (proposition, connective, argument, discourse layer etc.) it presents the main areas of problems arising during the IDR annotation that are the consequence of the specific form of the existing (especially tectogrammatical) PDT 2.0 annotation.
