CiteSeerX - Document Details (Isaac Councill, Lee Giles): The paper presents how we can model Concurrent Constraint Logic Programming (CCLP) using the formalism of Attribute Grammars (AGs). For this, we present PAGE, a general Parallel AG Evaluator. ... Each program is transformed into an equivalent Attribute Grammar.
