This has the potential to increase modularity with respect to linguistic description and grammar engineering, and to facilitate concurrent processing and the treatment of ambiguity. 1 Introduction We introduce the new grammar formalism of Exten- sible Dependency Grammar (XDG). In XDG, com- plex phenomena arise out of the interaction of sim- ple principles on multiple dimensions of linguis- tic description. In this paper, we point out how this novel methodology positions XDG in between multi-stratal approaches like LFG and MTT, and mono-stratal ones like HPSG, attempting to com- bine their benefits and avoid their problems. It is the division of linguistic analyses into dif- ferent dimensions which makes XDG multi-stratal.
