XML_XSLT_Wrapper backend for Saxon w/ command line

Hi, there's a class I wrote long time ago that utilises Saxon XSLT processor via command line. http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/oc4ware/liboc4ware/Publication_Repository/1/OC4_PUBLICATION_REPOSITORY_Docbook_Saxon.php?rev=HEAD&content-type=text/vnd.viewcvs-markup Maybe this can be added as a backend to the XML_XSLT_Wrapper package once I adapted the class? If so, then I'd suggest to make a distinction in the factory method between Saxon_CL (for Saxon via command line) and Saxon_Ext (for Saxon via PHP Java extension as a future backend). Note that this class works with Saxon 6.x only. So we might even have to distinguish between Saxon versions in XML_XSLT_Wrapper::factory() due to API changes from Saxon 6 to 7? Sandro
