Hi Walt,

Cheers,

PS - Currently, notes from Walt at Samsung appear to
be blocked by a Sharp Labs spam filter - Craig and I are
looking into this - if anyone should see a note from Walt
to me at my Sharp Labs address that I haven't answered
please forward it directly to me - thanks.

<ira>
Excellent question - when we developed the PWG Process/2.0
we purposely did NOT specify just "how much constitutes a
prototype" (unlike the IETF or ISO), because we just wanted
at least one PARTIAL prototype before advancing to PWG
Candidate Standard - implement as little as you want, based
on the minimal requirements of the 'icMIBCompliance' macro.

<ira>
ANY service can implement extra counters - the Abstract Counter
spec (and the Counter MIB) tried to specify just the _minimum_
required counters for each service (i.e., only one unit of work).

<ira>
Yes - only 'workTotals(3)' is required - this should be described
in the MIB (though hard to do, because the work type is an INDEX
and therefore can't have an OBJECT clause in the MODULE-COMPLIANCE
macro, because it's not a visible object).

The authoritative implementation requirements are specified in
Section 8 starting on page 43 of the PWG Abstract Counters spec
"cs-wimscount10-20050923-5106.1.pdf".
