The constraint

What is actually in the way.

The part

What it is

The test of a constraint is whether removing it would change what is possible. Anything that would still leave the same limits is a symptom.

Stating it without a solution embedded is the discipline — a description that already implies what to do is a proposal in disguise.

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.
