By default, DITA2Go does not include descriptions with links. To include text from map desc, shortdesc, or linktext elements:
[RelatedLinks]
; UseRelDescription = No (default, do not include any descriptions)
; or Yes (include description from map shortdesc, linktext, or desc)
UseRelDescription = Yes
To include shortdesc content in the title attribute of the heading it applies to, instead of as a paragraph following the heading:
[RelatedLinks]
; UseRelDescAsTitle = No (default, treat descriptions as text if used)
; or Yes (use descriptions without formatting as title attributes)
UseRelDescAsTitle = Yes
When UseRelDescAsTitle=Yes, the shortdesc text appears with a mouseover in HTML output. This setting is effective only if you also set UseRelDescription=Yes.
Note: For the topic itself, the shortdesc always appears after the title, unless you specify otherwise; see §6.12.2 Including shortdesc content in the title attribute.
