XACML is popular as a fine grain authorization method among the community. XACML describes both an access control policy language, request/response language and reference architecture. The policy language is used to express access control policies (who can do what when).
Who uses XACML?
Those include Oracle, Axiomatics, Boeing, Veterans Administration, EMC who are regular contributors. DATEV (a german IT service provider w 5800 employees) announced in 2010 that they will use XACML.
How XACML works?
XACML is primarily an attribute-based access control system (ABAC), also known as a policy-based access control (PBAC) system, where attributes (bits of data) associated with a user or action or resource are inputs into the decision of whether a given user may access a given resource in a particular way.
Why XACML?
XACML enables use of abstract logic to determine whether or not to grant requested access and enables true fine-grained attribute and policy-based access control. But using XACML can be tricky in several aspects.

Can a role based access control be implemented in XACML?
Role Based Access Control ( RBAC) can also be implemented in XACML as a specialization of ABAC . The XACML model supports and encourages the separation of the authorization decision from the point of use.
Which is the open source implementation of XACML in Java?
“Balana” is one of the XACML implementation (with partial XACML 3.0 version) which is java based open source project. Therefore you can use it freely and you can find the source core from https://svn.wso2.org/repos/wso2/trunk/commons/balana/.
How are policy information points acquired in XACML?
The policies are acquired via the Policy Retrieval Point (PRP) and managed by the Policy Administration Point (PAP). If needed it also retrieves attribute values from underlying Policy Information Points (PIP). The PDP reaches a decision (Permit / Deny / NotApplicable / Indeterminate) and returns it to the PEP
