XSL is a data-driven process (document order, etc.).  It is a very common
pattern to massage data for a subsequent set of templates, the prevalence of the
node-set() extension attests to this.  The good news is that chaining a pair of
Sax tranformations allows one to use this technique without the necessity of
writing a file.  I think a two-pass transformation can be at once more
maintainable, more flexible and more efficient for a class of problems.
