In another system, I've implemented an operator that works kinda like a
"runto" value. Each rule in the pipeline definition has a numeric
ID, and when the runto is set, it will execute the pipeline up to that
point.

For example, if you have a pipeline:

  100 openoffice->xml conversion
  200 transform via per-page xsl
  201 transform via root xsl
  300 postprocessing

and you use "runto=100" in the URL, it will show you the XML after the
OpenOffice conversion. You could hold on to the existing passthru to show
the original openoffice file (or you could use "runto=0" instead,
conceivably).
