    <Paragraph position="0"> In this paper, we have very briefly presented an extended architecture for generation that attempts to combine generic methods for data-driven organization with top-down organizing principles. There are several further lines of development that are now required to establish the full utility of the architecture. At present, we have not evaluated the kinds of variation that occur when aggregation is sought at all levels of representation as we propose: in particular, generic text stages and grammatical structures have not been included. In addition, the relationship between the top-down communicative goals and the particular selections of organizing dimensions to be exploited during aggregation needs further work. Nevertheless, it seems clear that, in its combination of modes and techniques of processing from the NL-generation and visualisation traditions, an improved level of overall functionality has been achieved.</Paragraph>
    <Paragraph position="1"> SThis is, of course, only a heuristic at this time and could easily require alteration--for example, with different communicative purposes or different output modalities (e.g., spoken language).</Paragraph>
    <Paragraph position="2">  Work in progress or preparation is now providing more efficient and robust implementations of the general dependency analyses and their encoding in graphical form, furthering the relationship between rhetorical structure and motivated layout, and seeking more empirically based statements of generic document layout, visualization and text type constraints that can provide more detailed constraints for the page generation process.</Paragraph>
