calibre already ships with python2-lxml -- python bindings for
libxml2 and
libxslt -- bundled into the binary distribution (and a linux source/distro install requires it as a dependency).
That would appear to be xslt 1.0 only.
In order to use Saxon -- or any other tool you have a specific attachment to that doesn't come with calibre -- you'd need to bundle it in the plugin, and most likely require the user installs a JVM separate from calibre, then fiddle with their environment variables on Windows.
I am not aware of any Saxon bindings for python, so it'd be subprocesses all the way.
You'll have to decide whether that is worth the additional benefits XSLT v2 brings.
