</SectionTitle>
    <Paragraph position="0"> In this paper, we have argued that a text planner that is based on the notion of communicative intention and on plan operators that explictly represent such intentions must also incorporate a sophisticated model of the heater's attentional state, and the ability to use this model in order to make decisions about whether or not to include optional information (satellites of presentational relations). We have motivated this claim using naturally occurring dialogues, and by experimental results from a simulation environment which implements a simple, but psychologically plausible model of attentional state. Future work includes extending the analysis to the whole range of presentational relations, defining precisely a hearer model that can be used in text planning and an associated algorithm that can be used by the plan operators, and a theoretical investigation of the interaction between textual hierarchy and attentional state.</Paragraph>
