After exhaustive searches with no results I have come here with this question. Is it possible to customize the dreaded error message:
 
Resource not found
 
No pipeline matched request cd/v at <map:mount> - file:/something/sitemap.xmap:###:##
 
Where should I look for information on how to write a more user friendly message. We have received complaints from users of our web site and staff inside our organization about this error message. Any and all help is greatly appreciated.
