I've been investigating the dejavu (djvu) format to find out if it could do what you mentioned. I asked the guys at Lizardtech (www.lizardtech.com) if they had some off-the-shelf product. They don't but they could do some custom job. Djvu has what is called "a hidden text layer". Since it is regular text, I figured there could be also xml markup. Linux has text-based djvu utilities. I think the tools to manipulate the hidden text layer are all Windows-based.
