The delete-link element can be added to a list when you want users to be able to delete records from that list. A link will be provided with each record in the list which, when clicked, will pop up a confirmation dialog asking the user to confirm whether they wish to delete the record. If the user clicks Yes, this record and all its child entities will be removed from the Datastore. The text for both the link and the confirmation dialog are configurable (Deleting Records from Lists).
