As an alternative, you can use a FileName marker, in which case the marker content specifies both the topic ID and the base file name of the split file that contains the topic (see §32.7.3 ).
In the absence of either marker, the default topic ID is the base split-file name, adjusted as for CSS class names; see §14.9.4 .
If you do not split files (see §14.8.2 ), nor insert markers for topic IDs, Mif2Go makes up an ID for each topic after the first (which uses the base file name). These generated IDs are of the form topic2, topic3, and so forth. This is not recommended practice.
To specify a default ID other than the base split-file name (but only for the first topic in a FrameMaker file), include the following option in a chapter-specific configuration file (see §31.1.1 ) located in the project folder:
