CCTS Requirement [S4] - p.76

CCTS Requirement [S4] states:

"Aggregate Core Components are a particular category of Core Components.
As such, stored Aggregate Core Components shall include all Attributes
of Stored Core Components."

I know we visited this one earlier this week, and I mentioned an
"inheritance" mechanism. I thought my impression was incorrect, but now
am revisiting it. What I believe this requirement is saying is that all
Core Component attributes listed in [S1] (p.75) apply not just to Core
Components, but to Aggregate Core Components as well. Does anyone see
this differently?

If not: I see the possibility of us having 2 Object Types in the
registry (CC and ACC) that both have the exact same set of attributes -
except (a) The different ObjectType values, and (b) ACC will have
associations to its Core Components (i.e. its Core Component
Properties). 

Having said that: Couldn't we define a "Core Component" ObjectType with
the attributes specified in [S1], and an "Aggregate Core Component"
Object Type that inherits from the "Core Component" ObjectType? Perhaps
we can add a new association "InheritsFrom".

Thoughts?
