Hi Pascal,
Thank you for your reply. I agree with your suggestions.
Cheers,

Hello Ines
Many thanks for your review.
I see this recurring point of adding references to the other detnet documents; I'm happy to follow this advice, noting though that these are forward pointers since the problem statement comes first.

[PT>] what about:
"
Forward note: The <xref target='I-D.ietf-detnet-architecture'>
DetNet Architecture</xref> is the document produced by the DetNet WG to
describe that model.

[PT>] Can we add after the latter sentence:
"
In other words, a Deterministic Network is backwards compatible with - capable
of transporting - statistically multiplexed traffic while preserving the
properties of the accepted deterministic flows.
"

[PT>] I'm not too inclined because this sentence is about a lot more than DP
encoding, ad because this is really fast forwarding a lot.

[PT>] You're right, that fit in both places.

[PT>] done
Many Thanks, Ines : )
