   This file contains the default Struts Validator pluggable validator
   definitions.  It should be placed somewhere under /WEB-INF and
   referenced in the struts-config.xml under the plug-in element
   for the ValidatorPlugIn.

   These are the default error messages associated with
   each validator defined in this file.  They should be
   added to your projects ApplicationResources.properties
   file or you can associate new ones by modifying the
