( or clone the stylesheet from cached copy, because compilation 
of the stylesheet is expensive operation ).

I guess ... "as needed"  is "if stylesheet file has been changed on disk - 
it is time to reload the stylesheet, if not - use the cached  copy" ?

If yes - PXSLServlet ( being invoked in 'simple' mode) 
implements *exactly*  this scenario.

When invoked in 'advanced' mode
it grabs the source XML file from SQL 
database instead of text file, but that's 
another story.

The source code is available at  www.pault.com/Pxsl/

It is work in progress, but mostly that progress 
happens in SQL part.

I'l not provide too much support for version 0.2, but will 
start providing support  for version 0.3 ( on the way ).

However,  if one is able to read 2 small and clear java files - 
the version 0.2 already has all the source code needed to suport  
the scenario you have described above.
