Title : HELD Identity Extensions

When a Location Information Server receives a request for location
information (using the locationRequest message), described in the
base HTTP Enabled Location Delivery (HELD) specification, it uses the
source IP address of arriving message as a pointer to the location
determination process. This is appropriate in many environments.
However, when an entity acting on behalf of the Target would like to
request location information then the source IP address of the
request will lead to wrong results. In other cases the IP address is
not the only identifier that serves as an input to the location
determination procedure.
This document extends the HELD protocol to allow the location request
message to carry additional identifiers assisting the location
determination process. It defines a set of URIs for Target
identifiers and an XML containment schema. As such, this extension
is used in conjunction with HELD to provide Target identification.
Examples and usage in HELD message syntax are provided.

In the body type:
"FILE /internet-drafts/draft-winterbottom-geopriv-held-identity-extensions-04.txt".
NOTE: The mail server at ietf.org can return the document in
MIME-encoded form by using the "mpack" utility. To use this
feature, insert the command "ENCODING mime" before the "FILE"
command. To decode the response(s), you will need "munpack" or
a MIME-compliant mail reader. Different MIME-compliant mail readers
exhibit different behavior, especially when dealing with
"multipart" MIME messages (i.e. documents which have been split
up into multiple messages), so check your local documentation on
how to manipulate these messages.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
Internet-Draft.
