We claim that existing specification lan- guages for tree based grammars fail to adequately support identifier managment. We then show that XMG (eXtensible Meta- Grammar) provides a sophisticated treat- ment of identifiers which is effective in supporting a linguist-friendly grammar de- sign. 1 Specifying tree-based grammars Whilst the development of standard unification- based grammars is well supported by the design of formalisms such as PATR-II, Ale or TDL (Krieger and Schafer, 1994), the situation is less well es- tablished for Tree-Based Grammars such as Tree Adjoining Grammars (Joshi and Schabes, 1997), Tree Description Grammars (Kallmeyer, 1996) or Interaction Grammars (Perrier, 2003). Roughly, two main types of specification for- malism for Tree-Based Grammars can be distin- guishe...
