Thanks guys, I stand corrected!  Perhaps it is better termed 
"Postel's Proposition" because of the rather large exception 
perhaps captured as "Bernstein's Anti-Corollary?"

I for one think that the Postel view is bad for 
interoperability as well because it leads to a loose and 
divergent community, which eventually leads to standards 
wars.  Oh joy...
