RE: [xsl] Omnimark vs. XSL (Saxon) Challenge

# It's a big program and I have a tendancy to think it's going 
# in an innefficient direction mainly by having all templates 
# except root be named and called explicitly with a whole lot 
# of variables being passed from template to template.  In my 
# limited experience, these slow down processing significantly.

I don't think there's any reason why calling named templates should be
inefficient. The thing to look at is the algorithmic complexity.
 
#  Someday I'll look into engine source and find out more specifically.
# Another suspicious piece that I've noticed is the calls like:
# 
# <xsl:variable name="random-nodes-r" select="document('')//*" 
# /> <xsl:variable name="random-nodes-c" select="document('')//*" />
# 
# Which, (correct me if I'm wrong here), are making two extra 
# copies of the entire document in a variable? 

No, only one extra copy. Calling document() multiple times with the same URI
will return the document from a local cache.
