The inclusions
What counts and what does not.
The part
What it is
Trials, internal accounts, cancelled orders, refunds and test data. Each is a decision and each is made differently by different teams.
The exclusion list is usually longer than expected and is where the definition earns its existence.
The smallest level
The attributes it carries
Each attribute is one of the framework’s shared types. What a date is, and how it is written, is defined once for the whole model — the note here says what it means in this particular place.
