The location
Where the rationale lives.
The part
What it is
In the design system next to the pattern, rather than in a document. A rationale a designer has to know about does not reach them.
A comment in the component itself is frequently the most effective place.
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.
