The transition

How a change is handled with people who worked towards the old one.

The part

What it is

Explaining what changed and why carries the effort forward; replacing the statement silently spends it.

Where the old vision was reached, saying so is a considerably better story than quietly moving on to the next one.

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.
