This slipup should be cleaned up now.

I haven't really been very much involved in the XML parsing bit of
libdaisy. I'll have to spend some time and look at how the parsing is
done. As I understood the ones who did the parsers, daisy books are
much like webpages - very few follow the standards. Unfortunately (I
think) the parsers might be a bit fragile if a book break the standard.

Some brainstorming regarding parsing and future development (I havent
thought out anything in any detail yet, but someone might find them

For future development, it could be interesting to see if we can use
(for example) tidylib to verify books and improve our parsing. We
might be able to fix some common errors or get informative error

We might also be able to replace much of the parsing with some sort of
XML transformation to an 'internal' format. If I'm not mistaken, they
are working on yet another Daisy standard now. I suspect it's easier
to maintain a set of XSLT-files rather than individual programmed

This should also lead to interesting possibilities when it comes to
ODF / OOXML. There's already an OOXML->Daisy converter that I suspect
use XSLT. Apparently, this enables MS Office-users to save documents
as Daisy-books.

In theory, we migt be able to do one better. If we do the
transformation in libdaisy we might be able to play (properly
formatted) ODF (and OOXML?)-documents directly and use something like
festival og espeak for audio output.

But, I'm a noob at linux application development and this is too
ambitious for me alone. This will require someone who know what
they're doing to get involved. :)
