Invitation to comment on XACML v3.0 Dynamic Attribute Authority v1.0

First public review - ends Dec. 31st

OASIS and the OASIS eXtensible Access Control Markup Language (XACML) TC are pleased to announce that XACML v3.0 Dynamic Attribute Authority Version 1.0 is now available for public review and comment. This is the first public review of this draft specification.

This specification defines a new XACML system component, the Dynamic Attribute Authority, which augments the request context of an XACML authorization request with additional attributes and attribute values that are generated on demand according to a set of rules. The rules are expressed as XACML policies, use obligations to specify the additional attributes and values, and are processed in the normal manner of a Policy Decision Point. This means that a Dynamic Attribute Authority can be readily constructed from existing XACML system components.

A primary use case for the Dynamic Attribute Authority is role enablement, where the dynamic attribute in question is the subject role.
