The mitigation
What reduces the impact without closing it.
The part
What it is
Telling the customer what will happen, warning them in advance, or apologising for it. Cheap and effective.
A seam the customer was warned about is experienced very differently from the same seam unannounced.
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.
