Yes, that's fine.  I think it's clear that we could have a 'verb' in 
the fragment "focus-on", "select" etc. to indicate that.  I think 
it's also clear that no matter what verb is used, the entire resource 
is 'available' to the UA, that scripts can (if they wish) navigate 
anywhere in the entire resource, and that UAs can optimize the 
interface for the given verb, but the interface can still permit 
access to the entire resource.
