Abstract
The paper describes a new implementation of feature structures containing disjunctive values, which can be characterized by the following main points: Local representation of embedded dis-junctions, avoidance of expansion to disjunctive normal form and of repeated test-unifications for checking consistence. The method is based on a modification of Kasper and Rounds ' calculus of feature descriptions and its correctness therefore is easy to see. It can handle cyclic structures and has been incorporated successfully into an envi-ronment for grammar development. 1
