Retrieving useful error information when compiling an xsl stylesheet in Saxon 9.

I am developing an application that uses Saxon 9 to transform XML with XSL stylesheets. I have so far been unable to extract useful stylesheet error information when an exception has been raised.

The Saxon 9 command-line utility produces very helpful error information including line numbers, diagnostics, etc, so I'm assuming that it is possible to extract the information through the java api somehow.

I've had a look at the various ErrorListener classes and related methods, but they only seem to deal with errors at transformation time. I may simply be after a nice way to run validation on the stylesheet text when I catch a javax.xml.transform.TransformerConfigurationException when compiling the stylesheet, but I've had no luck finding validation inside the Saxon classes either.

If I could get an example of extracting a stylesheet's error information during the compile phase that would be excellent.
import net.sf.saxon.*;
import javax.xml.transform.*;
import javax.xml.transform.dom.*
TransformerFactoryImpl fact = new TransformerFactoryImpl();
DOMSource source = ...;
// an XML document, already validated as XML
// to be used as the XSL stylesheet
try {
    fact.newTransformer(source); // 
} catch(TransformerConfigurationException error) {
    // I would like to extract xsl-related errors here
