I have reviewed this document as part of the security directorate's
ongoing effort to review all IETF documents being processed by the
IESG.  Document editors and WG chairs should treat these comments just
like any other last call comments.

This document specifies an extension to the Presence Information Data
Format Location Object (PIDF-LO, RFC 4119) so that location
information can be given relative to a base point. It is pretty
general, allowing the relative location to be various shapes or
specified with a map. Both XML and TLV representations are provided.

The Security Considerations section seems reasonable to me for a data
format specification document. It refers to the base RFC 4119
specification be also briefly touches on a covert channel that the
representation would otherwise have made available in some cases.

I feel comfortable with the existing Security Considerations section.
