We describe a new framework for de- pendency grammar, with a modular de- composition of immediate dependency and linear precedence. Our approach distinguishes two orthogonal yet mutu- ally constraining structures: a syntactic dependency tree and a topological de- pendency tree. The syntax tree is non- projective and even non-ordered, while the topological tree is projective and partially ordered.
