The fm-link element is used to create a FrameMaker-style cross-reference as a related-links item. On file save, this converts to a standard DITA link element and on file open, it converts back into an fm-link element. The way an fm-link is identified as such is the type attribute value which is given the format of “fm:<format name>”. Where <format name> is the cross-reference format name as defined in the FrameMaker template. When an fm-link element is inserted, the standard FrameMaker Cross-Ref dialog displays, select the target element and the cross-ref is inserted as a fm-linkref element (child of fm-link). You can optionally add a standard desc element as a sibling of the fm-linkref.
To use the fm-link feature requires the creation of fm-link and fm-linkref elements.
The fm-link and fm-linkref elements should be added to both the Topic and Book applications.
