<span class="fn">Some Name</span> is parsed the same in any  
microformat.  But names of people are more complex than names of  
songs, so they have additional parsing rules to account for the  
additional markup options.  That doesn't change the meaning of <span  
class="fn">Some Name</span> at all.

Ducks and horses are two different things, but we use the same term,  
"animal," to refer to both.  FN is a similarly generic term.

The meaning is determined by the markup, not the parsing.

It doesn't.

No.  Every browser parsers a given HTML document differently, but the  
HTML document still means the same thing.
