Thus, this may mean an exception with an XML-quoted stack trace.

There are two reasons, I prefer the stack trace in the response:

  *  the immediate correspondence between the request and the
     response containing essential information to analyse the problem

  *  newbies

     Even with the stack trace immediately in the response, they
     report problems with no or missing essential details about
     the problem.

     This will become worse when the error information is hidden
     in a log.
