  abstract  = {In this paper we design a syntax definition formalism as a family of formalisms. Starting with a small kernel, several features for syntax definition are designed orthogonally to each other. This provides a framework for constructing new formalisms by adapting and extending old ones. The formalism is developed with the algebraic specification formalism ASF+SDF. It provides the following features: lexical and context-free syntax, variables, disambiguation by priorities, regular expressions, character classes and modular definitions. New are the uniform treatment of lexical syntax, context-free syntax and variables, the treatment of regular expressions by normalization yielding abstract syntax without auxiliary sorts, regular expressions as result of productions and modules with hidden imports and renamings.},
