8 Conclusion
</SectionTitle>
    <Paragraph position="0"> We argued in this paper that sophisticated microplanning techniques are required even for mathematical proofs, in contrast to the belief that mathematical texts are only schematic and mechanical. We demonstrated why paraphrasing and aggregation will significantly enhance the flexibility and the coherence of text produced. In order to  carry out appropriate textual rearrangement we need a representation formalism which allows flexible but principled manipulation of linguistic resources. To this end, we basically adopted the Text Structure of Meteer, but split her semantic categories into two dimensions following Panaget. The type checking mechanism of Text Structure allows us to achieve paraphrasing by building comparable combinations of linguistic resources. Specified in terms of Upper Model concepts, our semantic aggregation rules are more abstract than similar rules reported in the literature.</Paragraph>
    <Paragraph position="1"> One important feature of our work is the integration of microplanning knowledge specific to our domain of application. This body of knowledge must be refined to further improve the quality of the text produced.</Paragraph>
    <Paragraph position="2"> More experience is also required to formulate strategies to choose among alternatives.</Paragraph>
