; box : a task or check that TPS names; TPX, the CAC or an agent performs it. The address at the end (5.5.2, row 19, SR3, CR9) says where TPS states it.
; parallelogram : a human act, a declaration, a review or a decision. Only a human does it.
; cylinder : a page or a record, something that exists on the wiki or in the register after the step before it.
; shaded, numbered region : a stage; its title carries the TPS addresses that govern it.
; solid arrow : the next step; its label is the condition or the outcome (pass, fail, match, mismatch, strike).
; dashed arrow : a return or a rejection path.

; state (rounded box) : a named condition a container or a block can be in; the arrow label is the event and its TPS address.
; filled circle, ringed circle : start and end.
; sequence lane : a participant (a human, TPX, a page, an agent); solid arrow an action, dashed arrow a reply or a check; a note is a rule.
