This is asking about the why and what. Prior debate focussed on
how. A step forward IMO.
  If ID's are a special case, the general idea of recognising
this point in a chunk of XML could be extended or refined as
a move forward (as Micah pointed out) to permit the recognition
of any point within the content of an element. I'm sure in 1986
the idea of identifying simply the start of an element was
a good step forward, today I'm not sure its enough. The 'why' 
it needs to be recognised (my view) solely relates to navigation
or location. 

What difference will that make to the question being asked?
How might XML move forward with a location identity (stepping over 
the idea of recognising a range) that enables not only the start of
an element to be located, but any point within that element.

Unsure about bringing ID's into it, but the idea of this sentance
is pretty cogent. Its certainly the right audience for the answer.
