Technical Summary

> When an emergency call is sent to a Public Safety Answering Point
> (PSAP), the device that sends it, as well as any application service
> provider in the path of the call, or access network provider through
> which the call originated may have information about the call, the
> caller or the location which the PSAP may be able to use. 
> This document describes data structures and a mechanism to convey such
> data to the PSAP.  The mechanism uses a Uniform Resource Identifier
> (URI), which may point to either an external resource or an object in
> the body of the SIP message.  The mechanism thus allows the data to
> be passed by reference (when the URI points to an external resource)
> or by value (when it points into the body of the message).  This
> follows the tradition of prior emergency services standardization
> work where data can be conveyed by value within the call signaling
> (i.e., in body of the SIP message) and also by reference.
