Subject: Re: [xacml-users] XACML 2.0 Policy/PolicySet version number

Hi Kamalendu.

Yes, the Version attribute is the policy revision number. It can be any 
dotted value like "1", "1.2", "" etc.

It serves two purposes. First, it's there to help you manage your 
policies and keep track of them as they progress. As you note, many 
revision control systems or repositories have similar features. Second, 
the version number can be used when you reference a policy. A 
PolicyReference element may require a specific version, a range of 
versions, or a minimum/maximum version.
