XML Access Control Markup Language. The 1060 kernel offers XACML to provide a generic, transport independent, policy-based access control model to applications and resources. XACML is available as a URA for use in XML applications.
XML Access Control Markup Language is a proposal for an XML syntax for specifying authorization and entitlements policies. XACML is expected to address fine grained control of authorized activities, characteristics of the access requestor, and the protocol over which the request is made.
eXtensible Access Control Markup Language. An OASIS standard for the expression of access control policies. It also contains a request/response protocol, and goes some way to specifying the actual components required (such as policy decision and enforcement points) in an access control infrastructure. It is a rich, but as yet, quite obscure and underused language.
