Hi David,
Thanks for the good comment (and the fresh eyes review :--) ).
Agree. We will update according your suggestion.

Having just looked at a 6-tuple concern in another draft, I noticed a 6-tuple concern in this draft:

5.4.2.  DetNet IP Flow Identification and Specification

   DetNet IP flows can be identified and specified by the following
   attributes (6-tuple) [I-D.ietf-detnet-ip]:

   a.  SourceIpAddress
   b.  DestinationIpAddress
   c.  IPv6FlowLabel
   d.  Dscp (attribute)
   e.  Protocol
   f.  SourcePort
   g.  DestinationPort
   h.  IPSecSpi

Not exactly - that's 8 items ;-).  The 6-tuple consists of items abdefg.   The simplest fix would be to remove "(6-tuple)" - beyond that, it might be better to remove that and add a couple of explanatory sentences after the list:

	The IP 6-tuple that is used for DetNet IP flow identification consists of items a, b, d, e, f, and g.  Items c and h are additional attributes that can be used for DetNet flow identification in addition to the 6-tuple.

Thanks, --David
