The items
Each distinct thing provided, product and service alike.
The part
What it is
Distinctness is the test: if a customer could receive one without the other, they are two items.
Bundled items should still be listed separately, because bundling is a decision that can be revisited only if the parts are visible.
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.
Item type
Product, service, support, access or term — the categories that get forgotten differ by type.
