[xsl] how to understand a complex stylesheet

[Michael Norman <michael.norman@xxxxxxx>]

Hello everyone.

I am writing a paper for university concerning mainly XSLT. 
One chapter is about getting into/understanding complex 
stylesheets. Since it is not easy to comprehend big 
stylesheets and it is often cumbersome to get acquainted 
with stylesheets, I am looking for ways to make this process 
easier. That is, I try to find ways like visualizing 
stylesheets or anything that is usable for understanding 
one. But it seems to me, that there is quite few information 
and research going on about this topic. I had a lot of 
problems finding anything, the only result I have so far is 
a SVG visualization by Chimezie Ogbuji, at 
http://www.xml.com/pub/a/2003/06/04/xslt-svg.html
Can anyone give me some hints or information about stuff 
like this? I would really appreciate your help!

Thanks in advanced,

greetings,

Henning
