We report on the initial stages of development of a robust parsing system, to be used as part of The Editor's Assistant, a program that detects and cor- rects textual errors and infelicities in the area of syntax and style. Our mechanism extends the stan- dard PATR-n formalism by indexing the constraints on rules and abstracting away control of the appli- cation of these constraints. This allows independent specification of grouping and ordering of the con- straints, which can improve the efficiency of process- ing, and in conjunction with information specifying whether constraints are necessary or optional, allows detection of syntactic errors.
