CONCLUSIONS AND FUTURE WORK
</SectionTitle>
    <Paragraph position="0"> We have presented a framework for handling three unruly phenomena: argument-order variation, optionality, and metonymy. Yet this framework is simple and does not sacrifice formal goals such as declarativeness.</Paragraph>
    <Paragraph position="1"> We are currently working on extending the mapping unit to other parts of speech such as nouns and adjectives. We are also working 4Our approach allows morn than a single complement constituent to appear at a given level, however, as the ditransitive VP rule above shows.</Paragraph>
    <Paragraph position="2"> ~Other systems which have a similar mechanism include the Lilog system of IBM Germany and the MLMo machine translation system.</Paragraph>
    <Paragraph position="3"> on more lexically-based ways to encode order, perhaps by a system of precedence among mapping units.</Paragraph>
    <Paragraph position="4"> Other furore work will include referential metonymy, the interaction of metonymy with anaphora, and non-constituent conjunction phenomena.</Paragraph>
