Good ideas.  Where do we put 3.2.3?

Hi Norm,
I like the structure now much better. See my comments in the ToC below.
- “3.1.x sections” are more tools to achieve QoS for DetNet, so what about to a second level section.
- “3.2.3. Packet encoding for service protection” does not really connected with the text/sections around it.
- I would change the order of 4.3 and 4.4.
- “5. Compatibility with Layer-2” could be a second level section in section 4.
Cheers

Checked in the stuff we talked about.  See what you think.
