I am not sure if this is a bug, but if not it's a feature request :-)

When the XSLT compilation fails (for example on the XSL error I considered as bug here https://saxonica.plan.io/issues/2676) I don't get any useful information from getErrorMessage().

The code

$result = $saxon->transformToString();

if($result == NULL) {
    $errCount = $saxon->getExceptionCount();
    if($errCount > 0 ){
        for($i = 0; $i < $errCount; $i++) {
            $errCode = $saxon->getErrorCode(intval($i));
            $errMessage = $saxon->getErrorMessage(intval($i));
            echo 'Error: Code='.$errCode.' Message='.$errMessage;
        }
        $saxon->exceptionClear();
    }
}

gives the error

Error: Code=Unknown Message=net.sf.saxon.s9api.SaxonApiException : Stylesheet compilation failed: 1 error reported

in the /var/log/apache2/error.log a more useful error appears:

Error at xsl:call-template on line 11 column 37 of style.xml: XTSE0680: Parameter xxx is not declared in the called template

Is it possible to make the getErrorMessage() function retrieve this error code?
