The transformation engine type is defined as a parameter for the transformation task, and
the dispatcher will send it to an appropriate engine where transformation is finally done.
This is demonstrated in the following code:
try {
stylesheetfile = task.getStylesheetLocation();
stylesheet = new XSLTInputSource(stylesheetfile);
xmlsource = new XSLTInputSource(reader);
}
catch (Exception e) { ... }
try {
...
XSLTResultTarget xmlresult = new
XSLTResultTarget(out);
