Hiya,

It's a nit so feel free to ignore me, but anyway... :-)

“identity” is a YANG term of art, see RFC 7950, Section 3:

Sure. Bad choice of a term though when it doesn't include
user@xxxxxxxxxxx but rather the 1701 value below. I guess
that ship has sailed though, but even so, for me this
document would have been clearer if it didn't repeat the
same (IMO) error. If you wanted a suggested change:

OLD

* identities

NEW

* Yang identities such as authentication-method that
  don't identify specific users/devices/people

But again, feel free to ignore me, the document doesn't
seem to me to have any worse privacy properties than
yang already has.

Cheers,

    o  identity: A globally unique, abstract, and untyped name.

Typical identities are essentially enumeration values of the protocols, i.e., code points that are text-based (in YANG-XML and YANG-JSON).  They are defined in the YANG module, and we need to give them SIDs to be more efficient.

These are the identities in ietf-system.sid:

1701,identity,authentication-method,
1702,identity,local-users,
1703,identity,radius,

1704,identity,radius-authentication-type,
1705,identity,radius-chap,
1706,identity,radius-pap,

These actually in a derivation hierarchy (see YANG excerpt below), but we don’t see that in the SID allocation.

If the latter were the
intent, then I'd have significant privacy concerns and this review would have
reached a "not ready" conclusion.
Indeed, but luckily these are not user identities.
