This document has been reviewed as part of the transport area review team's
ongoing effort to review key IETF documents. These comments were written
primarily for the transport area directors, but are copied to the document's
authors and WG to allow them to address any issues raised and also to the IETF
discussion list for information.

When done at the time of IETF Last Call, the authors should consider this
review as part of the last-call comments they receive. Please always CC

This document is ready with nits.

At a high level, the document describes the relationship between DetNet flows
and the underlying layer 2 network when that network is an IEEE time-sensitive
network, which is interesting because both DetNet and TSN require explicit
routing and resource allocation at different layers.

Two nits:

1. There are numerous and often significant grammatical errors throughout the
document. The working group should perform a scrub of the text to minimize
editorial load on the RFC Editor.

2. Informational documents containing (lowercase, non-authoritative) normative
language should provide clear references to corresponding normative sources for
all such statements. Ideally, to minimize future document updates, replicating
such language in non-authoritative documents is not advisable. That said, you
should consider whether this document is really informational or should instead
be standards-track.
