Fundamental question about EDD - why localized? Will this cause problems in other languages?

Hi,

I am running a German version of FrameMaker. All commands in the EDD appear in German. What happens when someone uses the EDD with an English or Chinese version of FrameMaker? Will this work as well?

If editors have a look at the EDD, do they see German commands or commands in their own language?

Can I simply change to English instead of German commands? 

Thanks for your reply.
