John, I guess your comment refers to the draft so I changed the subject.

If you want to be sure the authors see your comments, you might want to
write to them directly. My reactions inserted below.

There is a kitchen sink aspect to this draft that worries me. Rather than
starting simple, with three or four generic service classes, the authors
have chosen to present the union of a number of diffserv deployment models.
I think that risks confusing operators by giving them too much complexity
to choose from.
