What is the use of function in XACML?
XACML comes with a powerful system of functions. Functions can work on any combination of attribute values and can return any kind of attribute value supported in the system. Functions can also be nested, so we can have functions that consume the output of other functions, and this hierarchy can be arbitrarily complex.
What is the XACML policy evaluation process?
XACML supports Attribute-Based Access Control (ABAC) and evaluation can be done with the additional data retrieved from Policy Information Point (PIP) which is defined by the XACML reference architecture. Policy Decision Point (PDP) evaluates policies against access requests provided by Policy Enforcement Points (PEP).
