Almost

You ask the RFC Editor to
"replace  reference to RFC XXXX, and draft-ietf-port-twamp-test "

I think that you mean
draft-ietf-ippm-port-twamp-test

I said that I was still thinking about secret-key and still am; I am
unsure what secret-key should look like.

There are two rival models for keystore.  RTGWG have produced RFC8177
which has

choice key-string-style {
...
     case keystring {
..
                   type string;
                   description  "Key string in ASCII format.";

     case hexadecimal {
..
                   type yang:hex-string;
                   description "Key in hexadecimal string format.


The NETCONF WG have produced a number of I-D, such as
draft-ietf-netconf-keystore, all of which have keys of type binary.

A YANG string, as this I-D currently references, limits the character
set of string which I do not think works without a binary or hex-string
alternative.

I note that
 draft-mirsky-ippm-twamp-light-yang
went for a keychain-ref while

draft-ietf-ospf-yang
has
 case auth-trailer-key {
...
               type string;
               description  "Key string in ASCII format.";
 without a hexadecimal alterntive which would seem to have limited
entropy.

Perhaps binary, as you had it originally, is best but I do think that
the IETF is confused, or conflicted, here.

Tom/Pete,

We believe this version of the draft addresses your comments.

Thanks.
