IMHO the clean way of doing this is to throw an Exception at the  
point where the success/failure decision is made, and use map:handle- 
errors with an ExceptionSelector to set the HTTP status code (See the  
errorhandling samples, http://cocoon.zones.apache.org/demos/release/ 
samples/errorhandling/).

I don't think there is a standard way of throwing Exceptions from  
XSLT code, but calling a small Java extension class from XSLT to  
throw the Exception should do the trick, if you need to do this from  
XSLT.
