Docbook -> EPUB 3

[Borden Rhodes <jrvp@bordenrhodes.com>]

Good afternoon,

I know that the XSLTs are still somewhat in beta because of the recent 
standards changes. All the same, I decided to SVN the entire source tree at 
http://code.google.com/p/epub-revision/ and run svn/trunk/src/spec/epub30-
overview.xml through:

xsltproc /usr/share/xml/docbook/stylesheet/docbook-xsl/epub/docbook.xsl 
epub30-overview.xml

(I use Debian Wheezy's docbook-xsl package, which I think is up-to-date).

As not to crowd the e-mail, I've summarised the errors at the bottom of this 
e-mail. I got an output, albeit with some conversions missing as detailed in 
the debugging dump. My question is to what extent are these errors problems 
with the source Docbook, which errors are due to inadequate support in the 
XSLT and which errors are due to me not using xsltproc properly?

With thanks,

Borden
