The willingness

Evidence about whether the customer would actually pay more for the gain.

The part

What it is

Stated preference overstates willingness consistently. Anything short of an observed trade-off should be recorded as an opinion.

A gain nobody will pay for is not necessarily worthless — it may be required for entry — but it should not be counted as a source of premium.

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.
