An interesting use case are documents including forms, that one may want to download from the web and fill in locally and off line, and resend the filled form as a package. This could probably be achived with EPUB-WEB, with the OWP technologies.
So maybe adding a few words about forms could be of interest.
Another use case are documents for which the editor wants to add protection (with a password or not allowing copy& paste, etc).
These are available in PDF and would also be of great interest.
Last is downloading of a subset of pages of a book in an EPUB
package. But maybe this is part of section "3.3 Document and fragment
identification"
