If we can come up with a way of using the string "foaf:name" without 
having to declare "foaf" in each document, I'm totally in agreement. I've 
considered maybe registering the "foaf" URL scheme, or using some other 
punctuation character and having people register prefixes, but I don't 
know what punctuation character to use (':' and '.' are both taken).
