  The APEX presence service spec states that presence entries contain
"one or more" tuples in them.  Why not zero?  And, if it must have at
least one, what should that default tuple be?  I'd think that a presence
entry with zero tuples would be the only way to indicate that someone is
unavailable (besides having a dummy-tuple with the 'availableUntil'
attribute in the past).
