it does give one possible answer, but whether it's a good enough answer 
depends on your requirements. it's simple in that it allows you to 
basically identify what you would graphically select with (possible 
multiple) rectangular selections in a spreadsheet UI. if you want 
something more fancy (in terms of selection or robustness against 
changes), it may not be what you're looking for.

on the web you can only identify based on media types and their fragment 
identification schemes, and these are per media type. in an ideal world, 
they would be across media types, allowing fragment identification to be 
robust across mechanisms such as content negotiation. i think pretty 
much everybody working with web resources did have this idea at some 
point in time, but that's not how the web works (at least not the web we 
currently have). i happen to think that there are good reasons why it 
doesn't work like this, but that's a different issue.

in terms of web architecture: since fragment identification is not 
robust across media types, the logical conclusion is that is you want to 
identify resources independent of media types, you have to turn them 
into full-fledged URI-identified resources.
