does this mean that for every non-back compatible implementation we  
will have an additional
command line flag or keyword? uhmmm...

This care won't be wasted updating to the a new CODATA set.
(I'm not an expert but I assume that the CODATA sets are internally  
consistent)
Sorry but yours is not the point.

well.. if you think so.. just open one of the many files consisting  
of duplications
(can send you the whole list if you like..) divide it in blocks of 20  
lines and start
cleaning them.. thanks!

nono.. better.. we can introduce each time a new command line flag...
