Hi Bill and Pete.
Bill - I like all of your new text.
However, there are two serious problems in existing text:
(1) Second paragraph at line line 5 of page 2 is just wrong
It is a StartupScanService operation (spelled that way) sent
to a System (NOT a ScanService) that creates a new instance
of a ScanService in the Initial phase, causes self-test, and finally
transition to Online phase / Idle state. The ScanService itself
does NOT perform a start-up operation (line 7). It is handling
the single E.startup *event* sent to it by the System (while in
in the Initial phase / Unknown state).
If we keep it, a RestartScanService operation could be sent
to a ScanService (to recover from a Shutdown to Offline
phase / Down state). See the notes on lines 1628 to 1639
on pages 66 and 67 of lcrc-mfdscanmodel10-20090119.pdf
(2) Recurring problem of reading the terms in state tables
The notation key in the Scan Service spec for the state table
is at line 1618 page 66 in lcrc-mfdscanmodel10-20090119.pdf
For example at line 12 in page 2 of your draft, we see:
"...either a C.Critical event is generated"
The expression "C.Critical" means a *passive* Condition (C)
(i.e., a ScanService.StateReasons value) is TRUE that a Critical
alert is now pending. While, the expression "~C.Critical" means
that any NOT (~) Critical Condition is now pending.
The expression "E.Critical" means that an *active* Event (E)
that is Critical has just occurred. Conversely "~E.Critical" means
that any non-Critical (i.e., warning) event has just occurred.
So "C.Critical event" is confused.
Cheers,
- Ira
