In order to provide a clickable label for the link element, the fm-linklabel element must be added to the EDD. This element is discarded on file save, and is recreated on file open.
The only thing required to implement this feature is to add the element definition to the EDD and to add it to the general rule of the link element. The fm-linklabel element should have a general rule of “<TEXT>”. If you want to apply character formatting you can add text format rules.
If this element is not added to the EDD, you will be able to create link elements, but they will have no label to click on.
The fm-linklabel element should be added to both the Topic and Book applications.
