Subject: Groups - XACML v3.0 Dynamic Attribute Authority Version 1.0 uploaded

Submitter's message
I've expanded the Architectural Considerations section and the Security and Privacy Considerations section. The technical content is the same. I still have to decide what to do when a dynamic attribute type is already in the request context.
-- Dr. Steven Legg
Document Name: XACML v3.0 Dynamic Attribute Authority Version 1.0

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.
