Their own process · The requirements · Element

The obligation

What has to be satisfied, stated as the requirement states it.

The part

What it is

Regulation, standard, certification, documentation format or contractual condition. The kind matters, because a regulation is fixed and a contractual condition is negotiable.

Written in the requirement’s own terms rather than summarised. A paraphrase loses the detail that decides eligibility.

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.
