I agree that it's an important issue. I agree that 2) would be a huge  
improvement over 1), and that 3) is a recipe for disaster.

Regarding Xiaoshu's point that 2) doesn't allow us to click on an RDF  
hash URI and end up scrolled to the right spot in the HTML: I agree  
that this is a problem. But I think it's a Web browser implementation  
issue, and can be worked around with in-browser trickery, such as a  
bit of Javascript. So I'd say there's no need to bend the architecture.
