COMMENT:
----------------------------------------------------------------------

Roman's comment is a good one.

Section 1

                         As described in [RFC8939] no DetNet specific
   headers are added to support DetNet IP flows, only the forwarding
   sub-layer functions are supported inside the DetNet domain.  [...]

nit: I suggest "so only the forwarding sub-layer functions can be supported inside the DetNet domain".

<Bala'zs> Thanks, I will fix this.

Section 4.2

   A TSN-aware IP (DetNet) node implementations must support the Stream

nit: singular/plural mismatch "A TSN-aware IP"/"implementations"

<Bala'zs> Thanks, I will fix this.

Section 4.4

   Implementations of this document shall use management and control
   information to map a DetNet flow to a TSN Stream.  N:1 mapping
   (aggregating DetNet flows in a single TSN Stream) shall be supported.

I note that in draft-ietf-detnet-tsn-vpn-over-mpls this was a normative "SHALL be supported" (which was itself the strongest criterion I could find for that document being standards-track).  Is there a simple description for what's different between these documents?

<Bala'zs> The major difference of these documents is the network scenario they focus on. IP-over-TSN and MPLS-over-TSN describes the scenario when DetNet nodes are interconnected by a TSN sub-network. These documents are on informational track and contains no conformance language. Whereas TSN-over-MPLS describes how TSN domains can be interconnected by a DetNet MPLS network and it is on standard track with conformance language.

Section 9.2

I agree with the other ADs that (most of?) the IEEE references should be classified as normative.

<Bala'zs> OK. This will be updated.
