[docbook-apps] EPUB3 only stylesheet collection?

[Mike Cook <m@mikecook.co.uk>]

I'm in the middle of writing a Ruby GEM for generating EPUB3 books from 
DocBook 5.x documents.

Starting out, it's just going to be the default DocBookXSL EPUB3 
transform, but I will eventually be customising them. Putting the whole 
1.78 archive in the GEM package is not really appropriate but I would 
still like to include all the needed files for generating EPUB3. Now, my 
XSL skills are pretty crummy so I got out the hammer and created a test 
collection by starting with just /epub3/chunk.xsl and adding the other 
files until xsltproc stopped complaining :)

Not a very clever approach I know, so I wanted to ask here if you have 
any pointers for pulling just the EPUB3 related files from the current 
archive?

Here's the file list I currently have, which works on the few test files 
I have - perhaps it's good enough to start with? Is there anything 
obvious that might trip me up?
