Hi everyone,

I'm currently looking at access control mechanisms of OpenStack and finding
that the access control policy is specified using JSON format.

I'm wondering why we do not adopt an XML based approach like XACML, is it
because of the performance problem, or we just choose JSON as it's simple?

Thank you very much for your feedback.

Best Regards,
