6 Conclusion
</SectionTitle>
    <Paragraph position="0"> Unlike previous approaches, the description language implemented by XMG is fully declarative, hence allowing to reuse efficient techniques borrowed to Logic Programming. The system has been used successfully to produce core TAG (Crabb'e, 2005b) and Interaction Grammar (Perrier, 2003) for French along with a core French TAG augmented with semantics (Gardent, 2006).</Paragraph>
    <Paragraph position="1"> This paper shows that the metagrammar can be used to put model theoretic syntax at work while preserving reasonably efficient processing properties. The strategy used here builds on constraining offline a TAG whose units are elementary trees The other option is to formulate constraints applied on-line, in the course of parsing, applying on the whole syntactic structure. In a dependency framework, XDG followed this path (Debusmann et al., 2004), however it remains unknown to us whether this approach remains computationally tractable for parsing with real scale grammars.</Paragraph>
