RE: [regrep-cc-review] CCTS Requirement [S4] - p.76

Joe,

Maybe you've something else in mind but I couldn't follow it.
IMO you should take Core Components (and its attributes) as
something abstract, thus you can't simply store a Core Component.
Instead, you have to decide whether to store a ACC or a BCC.
Still you can see them both as Core Components.
