Some initial  thoughts on this I-D

Prefer 'Abstract' before 'Copyright' and 'Status'

   | acl       | ietf-access-control-list | [I-D.ietf-acl-yang] |
better to have
   | acl       | ietf-access-control-list | [RFC YYYY] |
Note to RFC Editor please replace YYYY with number assigned to draft-

YANG module needs the Copyright statement

4. IGMP and MLD YANG Modules
suggests that there are two modules but I only see one

      import ietf-inet-types {
and other imports need a reference clause to identify the RFC; for acl
you need such as
RFC YYYY "Network Access Control List (ACL) YANG Data Model",
Note to RFC Editor please replace YYYY with number assigned to draft-
( you can put all RFC Editor Notes in one place at the front - they
prefer it this way)

      revision 2019-01-03 {
there must only be one revision clause stating 'Initial revision' with
date of publication supplied by RFC Editor to match that on the file

several lines are too long e.g.
             If QQIC >= 128, QQIC represents a floating-point value as

5. Security Considerations
   transport is TLS [RFC5246].
this is now superseded

6. IANA Considerations
   Names registry [RFC7950]:
this is a poor reference since all it does is tell you to go to RFC6020;
better to tell the reader to go straight there.

   [I-D.ietf-netmod-rfc6087bis] Bierman, A., "Guidelines for Authors
this is now out of date - RFC8407
(and it tells you to do most of what I have listed above:-)
