We're not communicating.  Where your sentence says "Internet Service
Provider", I want it changed to "calling network service provider".  It is
the network that would add location and route calls, not the ISP.  The ISP
supplies location in both scenarios.  The difference is to whom (the end
device or the proxy in the calling network).

Yes, I think we all agree, and agree that my original sentence was 
poorly constructed.

Updated proposal:

This document describes an architecture for emergency calling in the 
typical Internet environment, in which the calling device bears most of 
the burden of implementing emergency calls, and the caller's Internet 
Service Provider has a supporting role.  The underlying specifications 
allow for the network to take a more expansive role in emergency calls, 
but such cases (and any associated issues) are not covered extensively 
in this document; rather, they are left for future study in other 
documents.
