Not necessarily indexed per se, but it's easy to skip large parts of a document 
because you know that it doesn't contain what you want.

Yes and no. XML doesn't stream all that well, because it doesn't fragment very 
well (you always need to send entire documents). For applications that can tune 
into a stream that has already started (any broadcast app for instance), that 
means they'd need to wait til the end of the current doc before they can start 
displaying anything. With binary infosets, that's not the case anymore. You can 
also update parts of a document more often than others and other such niceties. 
A lot of it is dependent on the transport layer, but binary infosets make that 
possible. I'm eagerly awaiting my first SVG TV ;)
