The manual
What a person checks.
The part
What it is
Keyboard navigation, screen-reader use, and whether labels and error messages actually make sense out of visual context.

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.
