private bool ToFromXmlDemo()

    bool returnValue = true;

    StrongNameIdentityPermission snIdPerm1, snIdPerm2;

    snIdPerm1 = new StrongNameIdentityPermission(blob, "MyCompany.MyDepartment.*", new Version(""));    
    snIdPerm2 = new StrongNameIdentityPermission(PermissionState.None);
    Console.WriteLine("Result of ToFromXml = " + snIdPerm2.ToString() + "\n");

    return returnValue;
