Yes indeed, XSLT-process caches the stylesheet for performance reasons
(running DocBook would be just a pain without this!).

To get the correct behavior when imported stylesheets are being used,
it would have to check for them. Unfortunately, the JAXP API doesn't
have any provision for this, and doing it at the processor layer is
very cumbersome and non-portable.

I'll think of an Emacs-based solution, something that looks for
imports in a stylesheet, and builds a dependency graph to be able to
correctly detect a modified imported stylesheet. If you see a better
solution please let me know.

In the meantime, you don't have to kill Emacs, just kill the *xslt*
buffer, or even better, touch the master stylesheet by saving it as
well.
