Essentially, having a separate set of headers for error output allows 
you to handle an error when it occurs, and not worry about it otherwise, 
by giving you a clean slate to work with when generating an error response.

Whether that's worth while or not is another question, but those are 
probably the circumstances under which it's useful to ahve separate headers.
