ABSTRACT
The paper introduces a grammar formalism for
defining the set of sentences in a language, a set
of labeled trees (not the derivation trees of the
grammar) for the representation of the ... string and elements of the set of subtrees
of the tree : such a relation is called a string-
tree correspondence. An example of a string -tree
