I have a drawback: clients MUST NOT render a resource if the URL has a 
fragment identifier and the client doesn't support fragments a la annodex. 
The reasoning is that the object within the clipping range and as a whole 
are different things, so rendering the whole without consideration to the 
clipping range would mangle the meaning of the URI.  So, to make this 
work, we'd have to make the few people who've shipped XSPF clients make a 
change, albeit small: they'd have to check for a fragment ID and skip the 
resource if they find one.
