Some attributes, called

+ target on candidate.
+ Single element reference attributes refer to a single Element. The rules to get the
+ attr-associated element for an element reference attribute attr and
+ element element, are: If the attribute is not specified on element, return null. If element has an explicitly-set
+ attr-element which is not null: If element's explicitly-set
