Not even the recursion? I sometimes find myself in the situation that 
recursion with only 20 levels deep can cause a lot of performance 
problems (at other times, this figure can be > 500 without causing 
performance issues at all). Especially with double recursion 
(fibonacci-like), but that's not the case here... I'd think that when 
the $section-paragragraphs is rather lengthy, the recursion becomes 
rather deep ....

Hmm, come to think of it, Matthieu, are you sure that the performance 
problem is in the XSLT process? Or is the output read by an XML 
processor of some kind that may choke on large input (or is the input 
fed to the XSLT processor from a DOM object, which can be rather mem and 
perf consuming)? Or do you catch the xsl:message messages with some 
messagelistener you wrote yourself (and perhaps does something more than 
only logging?).

In other words: can you run the stylesheet as bare as possible (i/o on 
local disk) and do you then still have the problems?
