The alternatives
The readings considered and not chosen.
The part
What it is
Each is written as a diagnosis in its own right, not as a summary. A one-line dismissal cannot be reconsidered later.
Two or three alternatives is normal; none usually means the chosen one was assumed rather than selected.
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.
