qualifier token a chosen word

reference price type

What the compare-at reference represents — a manufacturer's suggested retail price, the prior list price, a was-price, a minimum advertised price, a recommended retail price, a typical price. A qualifier of the sale-price host; a filterable category, so a token from a growing vocabulary (legal disclosure rules differ by reference type).

Reference price type is answered with one word chosen from the reference price types list — the same word shared across every product that uses it.

It is a qualifier of sale price — it has meaning only inside a sale price statement, one per statement, never on its own. It belongs with sale price to pricing — what it costs.

It is answered inside every sale price statement, not as a standalone question on a kind.
