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.
