Re: [xsl] Using Saxon 2.0 with FOP, XEP, Antenna House

Certainly in the case of FOP, it's possible to pass the data between Saxon and 
FOP at the level of SAX events. I used to package this in the product, but 
abandoned it because it wasn't possible to do the integration in a way that 
worked across FOP releases.

I suspect that any slowness you experience is more to do with the Java VM 
startup cost than with the extra cost of XML parsing and serialization; but 
that's conjecture.
