I am looking at this, and it feels like a wrong direction to go, especially if we want to generalize multi-file export to non-pages as well (e.g. formula exported as mathml file and as a link inside actual exported .odt file). Let's try to do it differently: 1. Introduce a new INFO plist field :multipage-pages - a list of extra pages to be exported in addition to the main document 2. Transocders can populate the list as needed, in addition to their normal return value, which may be a link to the page, for example 3. "pages" in the list, can be constructed using `org-export-with-backend' or other usual means to export data. 4. org-export-as will process all the pages from :multipage-pages in addition to the one returned by `org-export-data'. I believe that this approach should be the least breaking and the most flexible.

Let me know how to proceed. With my idea above, we handle the actual page rendering to a custom backend, which can reuse the normal TOC machinery, possibly encapsulated into sub-backend parameters. We can provide any additional info that is necessary within such sub-backend. Do note that we should not assume that each page corresponds to a headline in ox.el.
