Link for inclusion of element content.
Mainly used to create variants and versions, but may also be used for information fragments that is used in several information modules, e.g. standard warnings.
The first anchor point, 'InclusionPoint', is always a element with the 'ihref' attribute filled out (with any content). The second anchor point, 'InfoToInclude', is the element which contains the information fragment to be included. The two anchor points must be of the same type of element, i.e. they must have the same generic identifier.
