Look at http://twiki.org/cgi-bin/view/Codev/CollaborationGuidelines
It has a series if INCLUDEd topics and each of those tolics has a level 2 heading.
All of those headings appear in the table of contents on the main page.
When I construct something similar under Dakar I don't get a TOC with the INCLUDED headings
I'm marking this as 'Requirement" since it is about how Dakar should render something to apepar the same as Cairo.
I just tried it and it works perfectly.
Can you provide a testcase?
