Where do you see this?  I don't find it in currency-proposal nor  
currency-brainstorming.  Wherever it is, I wouldn't worry about that  
becoming a standard, as it doesn't make any sense.

I don't believe there are any microformats that encourage abbr for  
non-equivalent content such as above.  If you know of any, please  
point them out specifically.  The abbr-design-pattern [1]  
specifically says "Avoiding using the abbr-design-pattern to re- 
encode human text or to hide data."  There are known issues with abbr  
being used for content that doesn't read well in screen readers (e.g.  
ISO dates) [1], but we don't yet have consensus around an  
alternative, so for now, we use abbr.
