Hi Frank

 

Yes. Either that, or it should be a straight line with no arrows representing an "interface" of interest (this is what I was originally thinking when I drew it).

 

Thanks for pointing this out, and sorry for the confusion. Will take the action to update.

I believe that Figure 1 in section 6 has the IF-PV interface arrow pointing the wrong way_ it doesn't connect anything.

Section 7 describes the IF-PV as:
Posture validator interface (IF-PV): This protocol acts as a
carrier for posture attributes between a Server broker and a
Posture validator that is not co-located in the NEA server.

Shouldn't the figure look like this?
