Hi,
I was concerned about epub2 readers when writing the epub3 stylesheets. The
EPUB3 standard includes provisions for backwards compatibility with epub2
readers, such as including the .ncx file and various metadata items. The
DocBook epub3 stylesheet tries to use all those features, so most epub2
readers can open and browse most output from DocBook's epub3 stylesheet.
However, if you use videoobject or audioobject in your DocBook source, those
generate epub3-specific output, and would not be understood by epub2
readers. I've found that most such readers just ignore that output and
still display the rest.
BTW, according to this article, Kobo has announced full support for Epub3 by
third quarter 2013:
http://www.digitalbookworld.com/2012/kobo-to-fully-support-epub-3-by-third-quarter-2013/
The article also says that "Hachette announced that by March 2013 all of its
new books would be in EPUB 3 format."

Regarding EPUB2 Stylesheets
In my experience with Hachette books, the kobo readers do not display the
EPUB3 files (mybe not docbook's, but generaly speaking)
So we got back to epub2
I have the IDPF test files that I run from time to time on the IPAD, the
closest EPUB3 compatible mobile reader, and a lot files are rejected
("unknown format.....").
My 2 cents
If you want you can send me some files, I will test them on IPAD and MOBO.

How do you define read fully?
How do you ensure forward compatibility so that the readers that support
epub3 will get a similar reading experience?

Is there any reason why not to use the epub3 stylesheets?
Thanks for your answer Carlos.
Well, I'm not sure if EPUB3 is that widespread than EPUB2. Older
EPUB readers does probably not support EPUB3, so I was a bit concerned
about compatibility.
As far as I can tell epub2 stylesheets are not being actively
maintained. Bob has done an awesome job with epub3 and thy should be
readable by older devices out of the box.
Probably I should move to EPUB3 anyway. :)
Thanks!
