Abstract: XML Declarative Description (XDD) theory employs XMLs nested tree structure as its underlying data structure and Declarative Description theory as a framework to enhance its expressiveness. It enables direct representation of data items, encoded in XML applications, and extends their expressiveness by materializing succinct and uniform representation of implicit information, integrity constraints, conditional relationships and axioms. With the aim of enhancing XDDs expressive power, this paper presents its extension with a well-defined mechanism for formulation of negative constraints (or negation). In addition, the formulation is employed to treat arbitrary XML first-order formulae in terms of corresponding XML first-order logical constraints (FLCs)...special kind of constraints which comprise XML expressions and logical symbols...Despite its expressiveness, XDD retains precise and well-defined declarative semantics. It achieves sound, efficient and flexible computation by means of Equivalent Transformation (ET)...a new computational model, based on semantic-preserving transformations. Basic ET rules for manipulation and reasoning with negative constraints are developed and certain examples illustrated.
