I've done the changes locally.  I could post a bugzilla request to make
the change go into CVS.

Yes, that needs more investigation.  But my current experience for
the old (current) version is that caching doesn't work right!  If I
change the configuration inside <map:components/> no new document gets
processed.  Cocoon is delivering an old, cached version :-/

Nothing to do... Hmm, to my knowledge the couple of
FragmentExtractor{Transformer,Generator} was created due to needs of
creating SVG images that are described inside the page.  So it's a
little bit historical.  But I agree with you, the extractor function is
not limited to svg processing -- I use it to store a fragment or the
whole document for later processing.
