15.2.1.6 Specifying the ID for a ditamap
By default, the ID for each DITA map is the base name of the FrameMaker file from which the map was generated. This is true for both book files and chapter files.
To specify a different chapter map ID, include the following setting in a chapter-specific configuration file named for the FrameMaker file (see §31.1.1 Providing configuration files for individual chapters):
; MapID = id for Frame chapter file ditamap, default is base file name
Alternatively, you can insert a DITAMapID marker in the FrameMaker file. The content of the marker becomes the id attribute for the map generated from the file, overriding any value specified for MapID.
To specify a different book map ID, in configuration file mif2htm.ini:
; BookMapID = id for book file ditamap, default is base book file name
You cannot use a marker to override the id attribute of a map generated from a FrameMaker book file.
