Title: XML Schema Based RBAC Approach

Abstract: The XML Schema expresses constraints and structures of XML
instances. Unlike its predecessor, DTD, it provides features such as
namespaces, built in basic types, keys and import facilities.Thus, in this
presentation, its expressive power to incorporate RBAC features will be
examined, as access control based on the schema will be transported to all
its instances. We will go over the extended RBAC model proposed in the
paper and introduce the author's newly included constraints to propagate
permissions to super and sub components. Finally, due to expressive
limitations four RBAC constraints this model is not able to handle will be
addressed.
