Résumé:
This paper describes a two-level formalism where feature structures
are used in contextual rules. Whereas usual two-level grammars
describe rational sets over symbol pairs, this new formalism uses tree
structured regular expressions. They allow an explicit and precise
definition of the scope of feature structures. A given surface form
may be described using several feature structures. Feature
unification is expressed in contextual rules using variables, like in
a unification grammar. Grammars are compiled in finite state
multi-tape transducers.
