May I step in here regarding the SAS:

If you use SAS dictionary (as you describe it) then *never* translate the words 
local languages because this will lead to SAS mismtach. For example if one 
party has
a English setup and thus uses the English words and the other party hase a 
setup then this party would use the Spanish words. In this case the parties 
compare the SAS and verify it.

It's of utmost importance to have *same* list of words on both sides. This
is the reason why the 4-character mode (base32) SAS is easier to handle 
Many people, even in arabic ountries for example, are able to spell single 
characters and digits but it's very hard for them to read the sometimes complex
English words.
