The message

The one thing, in its agreed wording.

The part

What it is

It should be recognisable as an expression of the position rather than a separate claim, or the two will pull against each other.

Held fixed, and quoted rather than paraphrased, for the same reason the position is.

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.
