by design xslt does not (can not) work in streaming mode: it needs to 
build up the input-tree from the sax-stream, transform that into an 
output-tree and then sax-stream that back out.

therfore a just-pass-all xsl will always be slower (and more memory 
consuming) then a just-pass-all sax filter

on the plus side: (so why use xslt at all, then?)
  - xslt as a language is more expressive and (why not being easy 
itself) often easier to write/maintain then a coded sax filter, 
specially for complex transformations
  - xslt as a standard is (my guess) in broader use (since more 
portable) then SAX event stream filtering


all in all, the simpler the task, and the less expected maintenance, 
modifications or extensions it will require: the more one should opt for 
coding things as a sax filter


Anyway, don't let these observations keep you from sharing your xslt 
solution (e.g. attached to the suggested JIRA issue) as it might be a 
quick win for a lot of people here and now

regards, and thx.
