    Subject: Re: [xacml] Comments on XACML v3.0 administration policy, Draft 06


    Thanks Anne,
    
    I have incorporated these suggestions in the latest draft which will be
    out in a moment. The only comment I did not address was the second to
    last one, since I am not sure what you wanted with that.
    
    Best regards, Erik
