5. Conclusion
</SectionTitle>
    <Paragraph position="0"> This paper has demonstrated the representation and processing of syntactic knowle, dge within the generation system POPEL-HOW which for the first time combines explicitly incremental sentence production with parallelism and feedback. Such a generation model imposes special requirements on syntactic representation and processing. A unification-based head-driven grammar, linguistically based on dependency grammar, is introduced that satisfies these demands. Furthermore the basic mechanisms for incremental and parallel generation have been presented.</Paragraph>
    <Paragraph position="1"> The whole generation system is implemented in Commonlisp on a Symbolics 3640 lispmachine by simulated parallelism using the process-facilities and the scheduler. It also runs in Kyoto Commonlisp and CLOS (using a selfwritten scheduler). The system is fully integrated in the natural language access system XTRA (cf. \[Allgayer et al.89\]).</Paragraph>
