Hi Andrew,

First a request - please compile this MIB with any SNMP compilers (from
SDKs, management tools, etc.) you have available.  I hate making ASN.1
errors that are avoidable.

Following IETF MIB convention, we always make whole element groups
one conformance level.

So, yes we *could* add the MaxXxxRecords to some new group (but
not the REQUIRED PowerGeneral group).

In review discussion at the October F2F, Pete Zehler and others seemed
to all agree that client-side implementers will ignore these properties.

My experience over 15 years writing private MIBs for 3 printer vendors has
been Pete's right - clients just try to create the row and handle the error
table full.

My Samsung implementers don't want MaxXxxRecords, because they
don't plan to use them client-side and they inflate the number of
REQUIRED elements (which looks bad to upper management).

- Ira
