Suppose you want to produce two tables of contents for HTML output: an overview and a more detailed TOC showing more levels of headings. You can differentiate the two TOCs in DITA by assigning them different outputclass values; for example:
<frontmatter>
<booklists>
<toc outputclass="overview" />
<toc outputclass="fulltoc" />
. . .
To identify generated lists for which you want DITA2Go to produce two or more booklist variants, you must:
For example, to distinguish two lists of figures:
<frontmatter>
<booklists>
<figurelist outputclass="schematics" />
<figurelist outputclass="assemblies" />
. . .
To assign each variant a name, see §14.9.2 Naming variant booklist components.
