The revision
What was added to the definition as a result.
The part
What it is
Usually a sentence. The definition grows by exactly the ambiguities the test exposes, which is the efficient way to write one.
Retesting after revision closes the loop and is quick.
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.
