You would want to have some kind fo markup that preserves structural markup as much as possible. I manage ebooks for a university press, and we have a deep backlist waiting for conversion, a lot of which only exists as page scans of old print volumes. I want to be able to offer them as epubs, which means I need to know where there are chapter breaks, heads, tables, charts, math, blockquotes, and so on and so forth. I have vendors that can do this for me, but it costs more than we'd get for some of these books in sales. I'd love to be able to do soem of this myself.
