The owner
Who defends the limit.
The part
What it is
Someone senior enough to decline a business case, since limits are tested by people with targets.
Without an owner the limit is defended by whoever happens to be in the room.
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.
