[cabfpub] RFC5280

[Rich Smith]

I can't speak intelligently to points 2-4, but as for #1, I get cases 
all the time where the legal organization name exceeds 64 characters.  
In addition to Netherlands, which Jeremy has pointed out, I see a lot 
from Germany, and given the unique method in the German language of 
stringing together several existing words to form a new word, things can 
get very long very quickly and are next to impossible to sensibly 
abbreviate.  Jeremy has pointed out a very real problem here.  I'm not 
necessarily advocating that we break from 5280 on this, but I definitely 
think it is worth attempting to update with PKIX/IETF.
