  the problem is that those bottlenecks are likely to be implementation
dependant, so generic profiling is unlikely to give good results (well
unless getting a model of the processor and running some serious
computations).

  xsltproc has a --profile [*] option where it dumps statistics about time
spent. The granularity is the template, not line blocks though. I'm
pretty sure Saxon also allow to gather profiling informations from a
run (I remember reading about it), but Michael Kay will certainly 
provide the details too :-)

[*] --norman is an alias for this option, guess why :-)
