Target
Description
In XACML all the attributes are categorized into four main categories:
A target can contains more than one subject, environment, resource or action or none of them. The target is the way to define the scope of an autorization policy. The result will be MATCHES if it all the target elements defined match.
- Attribute Designator: lets the policy specify an attribute with a given name and type, and optionally an issuer as well.
- Attribute Value: contains a literal attribute value.
