19.6.6 Mapping links to text insets
If your document includes text insets imported by reference, and contains links to those text insets, provide settings in section [XrefFiles] to map the insets to their containers.
For example, suppose Mydoc.book contains the following files:
Chap1.fm, which imports insets from file Boiler.fm
Chap3.fm, which imports insets from file Trouble.fm
Suppose you have cross references or other links (working properly in FrameMaker) to, from, and between insets. You would specify these settings in the configuration file:
That is, you need only specify the container file for each inset. As long as all cross-reference markers (and hypertext newlinks) in insets are accessible from the container by normal means (for example, gotolink), this is all you need to do. If links are made only from insets to their containers, you do not need any [XrefFiles] entries.
