    {
        // Extract the action URI from the OperationContext. Match this against the claims
        // in the AuthorizationContext.
        string action = operationContext.RequestContext.RequestMessage.Headers.Action;
        Console.WriteLine("action: {0}", action);

        // Iterate through the various claim sets in the AuthorizationContext.
        foreach (ClaimSet cs in operationContext.ServiceSecurityContext.AuthorizationContext.ClaimSets)
        {
            // Examine only those claim sets issued by System.
            if (cs.Issuer == ClaimSet.System)
            {
                // Iterate through claims of type "http://example.org/claims/allowedoperation".
                foreach (Claim c in cs.FindClaims("http://example.org/claims/allowedoperation", Rights.PossessProperty))
