[uf-dev] implied-n: what's in a name?

[Drew McLellan]

The first implied-n optimisation rule states:

 > The content of "FN" is broken into two "words" separated by  
whitespace.

My question is - what's a word? Obviously whitespace delimits a word,  
but is any non-whitespace value permitted? How about punctuation and  
numbers?

An example I just ran across is fn="Sarah-Jane Smith". Am I safe to  
imply n from that?

So many questions! :)
