The following is a proposal for XACML Extensibility.
XACML Extension Model that defines what portion of the XACML specification
is a core and to what extent the XACML specification can be extended. Based
on this proposal, XACML policy administrators can represent much broader
access control policies by extending the core portion of the XACML
specification.
This extension model is designed to support an XACML extensibility property
stated in the XACML charter. This proposal is based on the current language
proposal document but includes several modifications.
I attach MS Word and PDF below.
