I studied this a while ago, and IIRC there was a problem with <xsl:message terminate=true> which calls the ErrorListener with an exception containing the message and terminates the processing with another one (catched by TraxTransformerImpl) which only states "stylesheet directed termination". Maybe the exception passed to the ErrorListener should be buffered to be rethrown at the end of processing.
