Has anyone tried any of the following?
- Repeating page numbers/names?
- Having them go backwards?
- Using words rather than numerals of either sort?
- Linking to extra documents not in the manifest or toc?
(For the last couple, I imagine trying to create a kind of ADE ePub "Easter Egg" where the only way to access certain content in the book is to type "xanadu" in the "Go to" box or similar.)
Probably this is all asking for trouble.
My experiments suggest that it's a bad idea to skip certain subdocs from the page-map... I tried to avoid the roman numerals problem just by skipping those pages in the page-map, but on my Sony, it just made the front-matter inaccessible entirely.
