The pricing basis
What is charged and on what basis.
The part
What it is
Fixed, time-based, volume-based or outcome-based, each of which creates a different incentive for the partner.
Time-based pricing rewards taking longer, which is worth naming even when it is the right structure.
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.
