I believe publication of this document may be harmful to the Internet.
In particular I believe that this document modifies data structures
used outside the context of Simple in ways that are specific to
Simple.  The presence documents that this data model modifies are part
of CPIM and thus are used for interoperability between multiple
instant messaging systems.  While I this document takes steps to avoid
interoperability problems, There are several potentially harmful
interactions with CPIM.

1) This document doesn't give advice on how to generate presence
documents useful both to watchers who understand this data model and
to watchers who do not understand this model.


2) This document doesn't give advice sufficient to implement watchers
that can make reasonable use both of CPIM style presence documents and
that can make use of the data model documents.

3) I'm concerned that the interactions when multiple IM/communications
systems start using this model have not been fully considered.


I was not able to determine that these issues had been considered
adequately so I am abstaining.
