Without an explicit heading, it would probably just have a placeholder text
like [no heading] and people can assume from the rest of the outline what
may be in that section - in particular a continuation.

I look at it like a book's table of contents. It could have its own section
or be used before any sections start. In books, the table of contents often
has its own section and is listed in the table of contents. It would create
a shadow dom with links to all the sections. In books they would also have
page number - when printing such a Web page, page numbers could be added,
but for online viewing they would just be links.
