So, you mean, your private list of issues is indeed finite?
Good news!! :-)

Ah, well, finite + n ... ;-)

Ah, good one, will fix that.  In short: 'Checkpoint' would
be a good example for a trigger.  Its not boolean: you never
notify an application 'Do no checkpoint now!' - but you use
the metric to trigger a checkpoint 'Checkpoint now!'.  I
guess this is equivalent to an attribute who's existence or
absence carries semantic meaning (e.g. 'Checkpointable').
That, however, maps pretty nicely to boolean attributes in
all cases I can think of ('Checkpointable=yes').

Does that make sense?

Thanks, Andre.
