Agreed, there are cases where this might be wanted as a response from an xpath expression. Hence a warning. Hence 'not all the time'. But consider the typo that we all make from time to time .... to time. If it can help find that, it helps debugging. Once you've stared at a stylesheet for minutes on end and read what you thought you wrote, rather than what you actually wrote.... Then any debug info helps! -- regards -- Dave Pawson XSLT XSL-FO FAQ. http://www.dpawson.co.uk
