Establishment of a link between anchors, for reference purposes.
Used to reference information, e.g. figure, section, module or external document. The referenced information can be a single element or entity, a span between two elements, or several elements or entities.
The first anchor point, 'ReferencePoint', is always a 'hanvisning' element. The second anchor point, 'ReferencedInfo' may be one or more elements or entities. If it is several elements, they are regarded as together constituting the referenced information. Several entities at the second anchor point is however regarded as alternative referenced information, i.e. the user (or possibly the application) must pick one of the entities.
