6 Conclusion and Future work
</SectionTitle>
    <Paragraph position="0"> This paper showed how cross-linguistic generalizations (in this case, V2) can be incorporated into a multilingual MG. This allows not only the reuse of MG parts for new (often, not well-studied) languages, but it also enables us to study small-scale parametric variation between languages in a controlled and formal way. We are currently modifying and extending our implementation in several ways.</Paragraph>
    <Paragraph position="1"> The Notion of Projection In our current approach, the verb is never at the basis of the projection, it has always been removed into a new location. This may seem unmotivated in certain cases, such as German verb-final sentences. We are looking into using the XMG unification to actually place the verb at the bottom of the projection in these cases.</Paragraph>
    <Paragraph position="2"> Generating Top and Bottom Features The generated TAG grammar currently does not have top and bottom feature sets, as one would expect in a feature-based TAG. These are important for us so we can force adjunction in adjunct-initial V2 sentences (where the element in clause-initial position is not an argument of the verb). We intend to follow the approach laid out in Crabb'e (2005) in order to generate top and bottom feature structures on the nodes of the TAG grammar.</Paragraph>
    <Paragraph position="3"> Generating test-suites to document our grammars Since XMG offers more complex object-oriented functionalities, including instances, and therefore recursion, it is now straightforward to directly generate parallel multilingual sentences directly from XMG, without any intermediate grammar generation step. The only obstacle remains the explicit encoding of Hypertags into XMG.</Paragraph>
