/**
 * MessageWarner is a user-selectable receiver for XSLT xsl:message output. It causes xsl:message output
 * to be notified to the warning() method of the JAXP ErrorListener, or to the error() method if
 * terminate="yes" is specified. This behaviour is specified in recent versions of the JAXP interface
 * specifications, but it is not the default behaviour, for backwards compatibility reasons.
 *
 * 

The text of the message that is sent to the ErrorListener is an XML serialization of the actual * message content.
