Re: Reusing XT instances

---

Hi Bob,

It depends on your context !

The XSLServlet works in a servlet environment which is multi threaded
and it wouldn't be safe to use the same object.

However, the longest operation is the parsing of the XSLT transformation
which is done before the XSLProcessor is cached and therefore, this
parsing is reused.

The driver is a different story since it's running in it's own java VM.

Hope this helps.
