Capacity to act · The reserve · Element
The usage
What it has been used for.
The part
What it is
Recorded, since a reserve never used may be too large and one exhausted early may be too small.
A reserve that is never used is also worth questioning: either no opportunities arise or they are not reaching the decision.
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.
