It's explicit - see section 3.8 of RFC 793. The issue with that variant 
is that it captures the state of TCP in 1981; it has evolved quite a bit 
since then. Although we do have a 793-bis in the works, the update of 
that section hasn't been tackled yet.

Let's put it this way:

	- if the goal of TAPS is to unify existing APIs,
	then those APIs need to be summarized together in one place


	- if TAPS is indeed focused solely on an alternate API,
	then it should NOT try to 'restate' the existing TCP API
	in a TAPS doc

"Do, or do not; there is no try."
	- Yoda
