XOM API for Processing XML with Java

[Elliotte Rusty Harold <elharo AT metalab.unc.edu>]

Brendan Humphreys ran the Clover unit test coverage tool across XOM. 
Results are at http://www.cafeconleche.org/XOM/clover_html/

One thing I noticed from this is that most of the exception no-args 
constructors aren't tested, which made me wonder is anybody using 
these? Would it be a good idea to just delete them all? This would 
have the effect of requiring a message to be specified for each 
exception that was created. That should be happening most of the time 
in the XOM code base now anyway.

Does anyone care to argue in favor of or against no-args constructors 
for exceptions? Can anyone point me at any references that discuss 
the relative advantages and disadvantages of allowing message-less 
exceptions?
