XACML 3.0 is now Committee Specification Draft

Good news! Version 3.0 of the eXtensible Access Control Markup Language (XACML) has just been voted a Committee Specification Draft.

I’ll update this list when I find more examples. If you know of any, please let me know.

Update 2011-08-19: BitKOO is the second vendor to attest 3.0 compliance, after Axiomatics.
