Example
To let a user select a billing address out of several addresses they have submitted, you could create an AQ_InstanceLinker that displays entity Address and attributes Address.Street, Address.HouseNumber, Address.City.
You would then add a Relation to your page or container and select "Customer", "HasBillingAddress", and this AQ_InstanceLinker:
The result would look like this:
Behavior before 10.7: The display text of the AQ_InstanceLinker is used as the question text of this relation, even if the linker text field is empty and the relation question field is not.
Behavior after 10.7: The display text of the AQ_InstanceLinker is only used as a header. (Blueriq 10.7 Release Notes, CSD-2135)
