RE: Meeting Minutes for the SMIng WG at the 49th IETF...

["Durham, David" <david.durham@intel.com>]

Hummm, the term "partial inheritance" was invented at the sming WG meeting.
It would be more correct to say sming allows partial implements of classes.
This seems no different than CIM, which allows optional properties (which
don't have to be used as I am told over and over again when I complain about
certain CIM properties :-) ). So, this concept is only relevant to the
mapping to say, SNMP... the class structure itself does not support "partial
inheritance" in sming. Juergen, pls correct me if I got it wrong.
