RE: number of tuples

I do have one small reservation about this.

Clearly, being "out to lunch" suggests that you are not available.
Considering that an automaton, for whatever reason, might be attempting to
ascertain your presence, it would better to provide a more easily digestible
state - one could argue that "out to lunch" is reducible to CLOSED in most
circumstances, and that therefore it should appear in a <tuple>. While
currently <note> can appear as a child of either <presence> or <tuple>, I
don't think the possibility of using <note> in <presence> was intended to
provide an alternative to <status>, a kind of out-of-band and
non-interoperable means of expressing status info. I always assumed <note>
was comparable to an 'away message' in existing IM systems - but in PIDF
that would presumably accompany an away <status> in a <tuple>.

Are there other motivating examples in which a <note> would appear as a
child of <presence> in which it does not effectively rephrase a <status>,
and in which there would be no need for any <tuple>s?
