Schema Based XML Security: RBAC Approach
As a platform-independent solution, XML is going to be used in many environments such as application integration and Web Services. Security of XML instance is a basic problem, especially in enterprise with large number of users and XML objects as well as complex authorizations administration. In this paper, a role-based access control (RBAC) model based on XML Schema is proposed.

Access control based on a schema will be transported to all its instances.
