The explanation
What the customer is told about why.
The part
What it is
Short and specific. “Based on what you viewed” rather than “recommended for you”, which explains nothing.
Shown at the point of personalisation rather than in a policy document.
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.
