The XML role-based access control (X-RBAC) specification language addresses multidomain environments' policy-specification needs. X-RBAC is based on an extension of the widely accepted US National Institute of Standards and Technology role-based access-control (RBAC) model. In addition to allowing specification of RBAC policies and facilitating specification of timing constraints on roles and access requirements, X-RBAC provides a framework for specifying mediation policies in a multidomain environment where RBAC policies have been employed.
