Yes

Set the |javax.xml.transform.TransformerFactory| system property by adding the following key-value pair into 
the run script:

$JAVA_HOME/bin/java -Xms64M  -Xmx1096M -cp $CP 
-Djavax.xml.transform.TransformerFactory=net.sf.saxon.TransformerFactoryImpl com.renderx.xep.XSLDriver $*

It will force XEP to use Saxon 9 (if it exists as jar in the java classpath).

There are other methods to load a concrete XSLT Transformer in Java. See, for example, 
https://stackoverflow.com/questions/29450535/what-is-the-default-transformerfactory for details.
