Is there a concept of reusing a Transformer instance?

[kroberts]

I've encapsulated some code that essentially emulates the xalan-1 API, to
minimize changes. There is a case where a reference to a class that wraps a
Transformer instance is copied; but now these two StylesheetRoot (the
wrapper) instances have references to the same Transformer reference. Is it
possible to do repeated transformations with the same instance. If not, is
there a concept of reset or clone?

Thanks.
