This property comes from IEEE-1275 and it's described use in that
spec is that the "sss" is human readable information.   So a message
as you described seems perfectly fine.  I've seen nothing that would
indicate a 3 digit error code is intended.

We plan to do a minor rev to the ePAPR in the near future and will 
clarify that when we do it.
