RE: [xsl] Stylesheet optimisation

["Michael Kay" <mike@xxxxxxxxxxxx>]

When the question is as general as this, I think one can only give very
general answers: make sure you know what the performance requirements are;
measure everything that's relevant; don't optimize anything unless you have
a performance problem; if you do have a performance problem, drill down to
where the problem is before you attempt any tuning. 

There are lots of hints and tips one can give for improving stylesheet
performance, but they may well not be relevant to your situation.
