I think some bits got dropped:

GDMO (CMIP's object definition language) supports multiple,
not partial, inheritance.  My point was that if attributes
have been bundled in a class, there must be some underlying
semantic that motivates this bundling.  To then "partially
inherit" from that class risks breaking whatever semantic
it was that led to the creation of the class in the first
place.

GDMO's way of handling multiple inheritance and packages
allows one to attain the same objectives without bastardizing
OO modeling with the kind of partial inheritance that's being
introduced here.
