The treatment
What happens to outstanding balances.
The part
What it is
Honoured in full, converted to something else, or forfeited. The middle option is usually available and usually acceptable.
Conversion at a fair rate to a discount, a credit or a product is received well and costs less than full redemption.
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.
