I think I should perhaps have added that whether you reuse the Transformer
really doesn't make a big difference. The important thing is to cache and
reuse the Templates object, which represents the compiled stylesheet. Doing
that is a very big saving, especially when the transformations themselves
run quickly (because the input documents are small).
