In this paper, we introduce an extension of the XMG system (eXtensible MetaGrammar) in order to allow for the description of Multi-Component Tree Adjoining Grammars. In particular, we introduce the XMG formalism and its implementation, and show how the latter makes it possible to extend the system relatively easily to different target formalisms, thus opening the way towards multi-formalism.

Mots clés: syntactic formalisms; tree-based grammars; metagrammars
