[keycloak-user] Does Keycloak compliant with XACML 2.0 or 3.0 standard?

Hello All, As per subject. I am also interested to know if Keycloak supports new features provided by XACML 3.0: Multiple Decision Profile, Policy combination algorithms, Delegation, etc. That being said, is aggregated policies feature is Keycloak's answer to some of the XACML 3.0 new features? Thanks
