Hi Bala'zs,
The modified text you suggest addresses my issue.
Thanks!

Hi Christer,
No, data plane specification does not cover what protocols are used by service sub-layer and forwarding sub-layer functions.
A data plane specification specifies what headers fields are there in the packet and how to use these header fields for a specific
purpose. For instance, in case of DetNet, what fields are used to recognize a DetNet flow (flow ID) and how is the sequence number
encoded and used.
A possible clarification is below (text added in brackets to firs sentence). Does it solves your concern?
OLD:
This document describes the concepts needed by any DetNet data plane
specification and provides considerations for any corresponding
implementation. It covers the building blocks that provide the
DetNet service, the DetNet service sub-layer and the DetNet
forwarding sub-layer functions as described in the DetNet
Architecture.

Hi Bala'zs,
Thank you for the reply and clarifications. I still have a question on Q2.
...
Q2:
>> The first line of the 2nd paragraph of the Introduction says:

>>
>> What is meant by DetNet data plane specification? The definition of DetNet flows over a specific network technology? Please clarify, or reference if already defined elsewhere.

The next sentence is fine. It is just a little unclear to me what the definition of DetNet data plane specification actually is. Is it a specification that
defines the combination of service sub-layer using protocol X and forwarding sub-layer using protocol Y?

Christer
