DOCBOOK-APPS: xsl reference question

After downloading the docbook slides dtd and xsl 
style sheets and creating a test presentation I attempted to render with 
xsltproc, which worked fine execpt for the duration.  Upon futher 
inspection it seemed in the xsl stylesheet 'slides-common.xsl' That is was 
referencing  the file 'chunk.xsl' from the net distribution at 
sourceforge.

 

I was successful in downloading the style sheets to 
my local machine and pointing the reference there, however in the process I have 
the following question.  What is the difference between the xsl style 
sheets in the slides distribution and the full xsl distro ?  Can I drop the 
two into the same path ?  Or is the slide-common.xsl stylesheet just 
'stealing' a component from the larger distro ?

 

Code now runs an order of magnitude faster 
!

 

Cheers
