The test

Whether it has ever actually been used.

The part

What it is

An authority that exists on paper and has never been exercised may not work in practice, and finding out during an opportunity is a poor time.

A small deliberate use is worth doing to establish that the mechanism functions.

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.
