+/**
+  * This <B>StyleSheetBatch</B> class supports multiple input/output files proceed by StyleSheet.main().
+  * It does work around the performance problems when running an extra saxon/JVM process for each file<p>
+  *
+  * The XSLT syntax supported conforms to the W3C XSLT 1.0 and XPath 1.0 recommendation.
+  * Only the transformation language is implemented (not the formatting objects).
+  * Saxon extensions are documented in the file extensions.html
