Balázs,

I can live with this, but have two snmall-ish comments.

  "DetNet uses flow-specific requirements..."

For me "requirements are something we documented and use to verify if an implementation is up to what we intended.

I think the sentence could be " "DetNet uses flow-specific parameterss..."

We also have

"POF configuration parameters – ... – are implementation specific."

I would say no, they can be more specific that that, they are service (or maybe flow) specific, at leas in theory a single implementation might support more than just one set of flow parameters.
