The list
Each condition the vision depends on.
The part
What it is
Stated as something that could be observed to have happened, so that progress on the vision can be read from progress on its conditions.
Ordered by dependency where one condition has to precede another.
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.
