qualifier token a chosen word

applies to payment method

The payment-method TYPE a price component applies to — a token from PaymentMethods (schema.org appliesToPaymentMethod). A qualifier of `price_component` only (reached solely via qualified_by; it declares no concern of its own and never enters slot-derivation), used to say that a component line is charged for paying a particular way: a `price_component` of type=surcharge with this qualifier set to `card` is a card surcharge; set to `cash-on-delivery` it is a COD collection fee. Absent on component lines that are not payment-specific (a base price, an eco-fee).
