Hi there,


I'm currently working on another draft ietf specification
(draft-ietf-dots-data-channel) which has a ordering requirement, but the
'ordered-by' statement is not specified (missing?)  for the 'list acl' in
container 'access-lists' in 4.1 IETF Access Control List


Container 'aces' has the 'ordered-by-user' statement for the list ACE.

      container aces {


          "The access-list-entries container contains

           a list of access-list-entries(ACE).";

        list ace {

          key "rule-name";

          ordered-by user;


            "List of access list entries(ACE)";



Container 'access-lists' does not have the 'ordered-by-user' statement for
the list ACL.

  container access-lists {


      "This is a top level container for Access Control Lists.

       It can have one or more Access Control Lists.";

    list acl {

      key "acl-type acl-name";


        "An Access Control List(ACL) is an ordered list of

         Access List Entries (ACE). Each Access Control Entry has a

         list of match criteria and a list of actions.

         Since there are several kinds of Access Control Lists

         implemented with different attributes for

         different vendors, this

         model accommodates customizing Access Control Lists for

         each kind and for each vendor.";



Is there a good reason why 'list acl' is not defined as sortable?

- or is it defined elsewhere as being sortable?

- or is the intention that there can only be one ACL?


We potentially have a requirement for multiple ACLs, each with its own set
of sorted ACEs where the ACLs cannot be configured in a random order and
need to know how to move forward.
