Exactly!  If that sentence appeared in a news paper article, which was 
made available online, it would appear like that.  It should need to be 
altered for the online version to use <span content="Tony Blair">Prime 
Minister</span>.

But what use case is there for a computer needing to determine from a 
sentence like that, that the "Prime Minister" is Tony Blair?  It would 
be quite clear to a human reading that in an article of some sort that 
Tony Blair is the Prime Minister without any additional markup.
