The change
What was changed at the collection point.
The part
What it is
Validation, a constrained list, a required field, or removing the field entirely where it is never entered correctly.
The last is underused and is frequently the right answer.
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.
