      ABSTRACT = {This paper describes a possibility of expressing ordering constraints among non-sister constituents in binary branching syntactic structures on a local basis, supported by viewing the binary branching structure as a list (rather than a tree) of constituents within HPSG-style grammars. The core idea of such a description of ordering is constituted by creating a type hierarchy for lists. The possibilities of expressing different approaches to word order in the framework are briefly discussed, exemplified and compared to other methods.}
